I have a report set with a parameter - Select # of WOs to display - 1, 2, 3, etc through 10.
 Issue  when you select 5  and there are only 4 WOs  no records return?
Thank you.

if shared stringvar rowsuppress_sv = '1'
  then {WORKORDER.REPORTDATE} <= nthlargest(1,{WORKORDER.REPORTDATE})
  else if shared stringvar rowsuppress_sv = '2'
         then {WORKORDER.REPORTDATE} <= nthlargest(2,{WORKORDER.REPORTDATE})
         else if shared stringvar rowsuppress_sv = '3'
                then {WORKORDER.REPORTDATE} <= nthlargest(3,{WORKORDER.REPORTDATE})

Try this

if shared stringvar rowsuppress_sv = '1'then
    {WORKORDER.REPORTDATE} <= nthlargest(1,{WORKORDER.REPORTDATE})
else if shared stringvar rowsuppress_sv = '2' then
(    
     if (Count(,{WORKORDER.REPORTDATE}) >= 2 then
         {WORKORDER.REPORTDATE} <= nthlargest(2,{WORKORDER.REPORTDATE})
     else
         {WORKORDER.REPORTDATE} <= nthlargest(Count(,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE})
)
else if shared stringvar rowsuppress_sv = '3'    then
(    
     if (Count(,{WORKORDER.REPORTDATE}) >= 3 then
         {WORKORDER.REPORTDATE} <= nthlargest(3,{WORKORDER.REPORTDATE})
     else
         {WORKORDER.REPORTDATE} <= nthlargest(Count(,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE})
)

Similarly for each N

Tried this but no success - please take a look at my formula - Thank you.
Questions
For this line do I put in the number 2, 3 etc?  -     (Count(2,{WORKORDER.REPORTDATE}),    
{WORKORDER.REPORTDATE} <= nthlargest(Count(,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE})

When I check validation of the report I get-  ) is missing -  after >= 2 then - then is hightlighted
)

if shared stringvar rowsuppress_sv = '1'then
   {WORKORDER.REPORTDATE} <= nthlargest(1,{WORKORDER.REPORTDATE})
    else if shared stringvar rowsuppress_sv = '2'then
    (if (Count(2,{WORKORDER.REPORTDATE}) >= 2 then
    {WORKORDER.REPORTDATE} <= nthlargest(2,{WORKORDER.REPORTDATE})
    else {WORKORDER.REPORTDATE} <= nthlargest(Count(2,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))
        else if shared stringvar rowsuppress_sv = '3' then
        (if (Count(,{WORKORDER.REPORTDATE}) >= 3 then
        {WORKORDER.REPORTDATE} <= nthlargest(3,{WORKORDER.REPORTDATE})
        else {WORKORDER.REPORTDATE} <= nthlargest(Count(3,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))
            else if shared stringvar rowsuppress_sv = '4' then  
            (if (Count(4,{WORKORDER.REPORTDATE}) >= 4 then
            {WORKORDER.REPORTDATE} <= nthlargest(4,{WORKORDER.REPORTDATE})
            else {WORKORDER.REPORTDATE} <= nthlargest(Count(4,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))
                else if shared stringvar rowsuppress_sv = '5' then  
               (if (Count(5,{WORKORDER.REPORTDATE}) >= 5 then
                {WORKORDER.REPORTDATE} <= nthlargest(5,{WORKORDER.REPORTDATE})

Since you have a ( after IF you need one before THEN

if shared stringvar rowsuppress_sv = '1'then
   {WORKORDER.REPORTDATE} <= nthlargest(1,{WORKORDER.REPORTDATE})
    else if shared stringvar rowsuppress_sv = '2'then
    (if (Count(2,{WORKORDER.REPORTDATE}) >= 2) then
    {WORKORDER.REPORTDATE} <= nthlargest(2,{WORKORDER.REPORTDATE})
    else {WORKORDER.REPORTDATE} <= nthlargest(Count(2,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))
        else if shared stringvar rowsuppress_sv = '3' then
        (if (Count(,{WORKORDER.REPORTDATE}) >= 3) then
        {WORKORDER.REPORTDATE} <= nthlargest(3,{WORKORDER.REPORTDATE})
        else {WORKORDER.REPORTDATE} <= nthlargest(Count(3,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))
            else if shared stringvar rowsuppress_sv = '4' then  
            (if (Count(4,{WORKORDER.REPORTDATE}) >= 4) then
            {WORKORDER.REPORTDATE} <= nthlargest(4,{WORKORDER.REPORTDATE})
            else {WORKORDER.REPORTDATE} <= nthlargest(Count(4,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))
                else if shared stringvar rowsuppress_sv = '5' then  
               (if (Count(5,{WORKORDER.REPORTDATE}) >= 5) then
                {WORKORDER.REPORTDATE} <= nthlargest(5,{WORKORDER.REPORTDATE})
                else {WORKORDER.REPORTDATE} <= nthlargest(Count(5,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))

COunt requires the field.  Delete the 2, and 3, etc

if shared stringvar rowsuppress_sv = '1'then
   {WORKORDER.REPORTDATE} <= nthlargest(1,{WORKORDER.REPORTDATE})
    else if shared stringvar rowsuppress_sv = '2'then
    (if (Count({WORKORDER.REPORTDATE}) >= 2) then
    {WORKORDER.REPORTDATE} <= nthlargest(2,{WORKORDER.REPORTDATE})
    else {WORKORDER.REPORTDATE} <= nthlargest(Count(2,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))
        else if shared stringvar rowsuppress_sv = '3'then
        (if (Count({WORKORDER.REPORTDATE}) >= 3) then
        {WORKORDER.REPORTDATE} <= nthlargest(3,{WORKORDER.REPORTDATE})
        else {WORKORDER.REPORTDATE} <= nthlargest(Count(3,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))
            else if shared stringvar rowsuppress_sv = '4' then  
            (if (Count({WORKORDER.REPORTDATE}) >= 4) then
            {WORKORDER.REPORTDATE} <= nthlargest(4,{WORKORDER.REPORTDATE})
            else {WORKORDER.REPORTDATE} <= nthlargest(Count(4,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))

Since COUNT produces a number you can't use NthLargest on it.

if shared stringvar rowsuppress_sv = '1'then
   {WORKORDER.REPORTDATE} <= nthlargest(1,{WORKORDER.REPORTDATE})
    else if shared stringvar rowsuppress_sv = '2'then
    (if (Count({WORKORDER.REPORTDATE}) >= 2) then
    {WORKORDER.REPORTDATE} <= nthlargest(2,{WORKORDER.REPORTDATE})
    else {WORKORDER.REPORTDATE} <= nthlargest(2,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))
        else if shared stringvar rowsuppress_sv = '3'then
        (if (Count({WORKORDER.REPORTDATE}) >= 3) then
        {WORKORDER.REPORTDATE} <= nthlargest(3,{WORKORDER.REPORTDATE})
        else {WORKORDER.REPORTDATE} <= nthlargest(3,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))
            else if shared stringvar rowsuppress_sv = '4' then  
            (if (Count({WORKORDER.REPORTDATE}) >= 4) then
            {WORKORDER.REPORTDATE} <= nthlargest(4,{WORKORDER.REPORTDATE})
            else {WORKORDER.REPORTDATE} <= nthlargest(4,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))
                else if shared stringvar rowsuppress_sv = '5' then  
               (if (Count({WORKORDER.REPORTDATE}) >= 5) then
                {WORKORDER.REPORTDATE} <= nthlargest(5,{WORKORDER.REPORTDATE})
                else {WORKORDER.REPORTDATE} <= nthlargest(5,{WORKORDER.REPORTDATE}),{WORKORDER.REPORTDATE}))

Could you please demonstrate where to take the "NthLargest" out of the formula.  Thank you.

if shared stringvar rowsuppress_sv = '1'then
   {WORKORDER.REPORTDATE} <= nthlargest(1,{WORKORDER.REPORTDATE})
    else if shared stringvar rowsuppress_sv = '2'then
    (if (Count({WORKORDER.REPORTDATE}) >= 2) then
    {WORKORDER.REPORTDATE} <= nthlargest(2,{WORKORDER.REPORTDATE})
    else {WORKORDER.REPORTDATE} <= nthlargest(2,{WORKORDER.REPORTDATE}),   {WORKORDER.REPORTDATE}))
