If I set up an index formula where i have to specify the bottom row, how can I automatically extend that as rows are added?

If there are no gaps in the data then you can do a count of data.

Hello,

you can use a match function to find the last populated cell in a column. If the data is text,

=MATCH("zzzz",A:A,1)

if the data is numeric,

=MATCH(99^99,A:A,1)

This can be plugged into the Index function:

=$A$1:Index($A:$A,MATCH(99^99,$A:$A,1))

You can also define a named formula with the match function. Create a name called LastRow with the formula

=MATCH(99^99,$A:$A,1)

and then use

=$A$1:Index($A:$A,LastRow)

cheers, teylyn

Hi teylyn

I never knew that something like

=$A$1:Index($A:$A,LastRow)

works. Thanks for this.

Hi Saqib, welcome to the power of named formulas! The beauty is that it is calculated once, but you can use it in many different formulas and don't have to repeat the match() in each one.

Saqib,

You can practice this new found information by re-writing the formula's you wrote for me over the weekend using this function!!  Will you do that?

I thought you gave up on me.  I sent you the below on Sunday.  You never responded.  So, I had to reach out to others.  (I like to deal with one person per spreadsheet so that I don't have to keep explaining the situation and re-uploading files.)  Below are my comments from earlier in the week.

That actually worked great.  I forgot to tell you one other piece of criteria. (Sorry.)

The actual formula is:
=IF(INDEX('6.14 All VDOTs'!$Z$2:$Z$352,MATCH(MAX(IF('6.14 All VDOTs'!$E$2:$E$352=G29,'6.14 All VDOTs'!$Y$2:$Y$352)),IF('6.14 All VDOTs'!$E$2:$E$352=G29,IF('6.14 All VDOTs'!$Y$2:$Y$352=1,MAX(IF('6.14 All VDOTs'!$E$2:$E$352=G29,'6.14 All VDOTs'!$Y$2:$Y$352)),'6.14 All VDOTs'!$Y$2:$Y$352)),0))=0,"In Flight",INDEX('6.14 All VDOTs'!$Z$2:$Z$352,MATCH(MAX(IF('6.14 All VDOTs'!$E$2:$E$352=G29,'6.14 All VDOTs'!$Y$2:$Y$352)),IF('6.14 All VDOTs'!$E$2:$E$352=G29,IF('6.14 All VDOTs'!$Y$2:$Y$352=1,MAX(IF('6.14 All VDOTs'!$E$2:$E$352=G29,'6.14 All VDOTs'!$Y$2:$Y$352)),'6.14 All VDOTs'!$Y$2:$Y$352)),0)))

Please revise it to add the criteria that:  If column Z=Dispute, the return the value in column T.

BTW: can you write in simply terms exactly what is going on in the formula?  I would love to understand it a bit more in case I have to make slight revisions as time goes by.

Finally, as the rows increase in the spreadsheet, is there an easy way to extend the range without having to manually increase 352?  [6/19 - I think the "Last Row" name trick you learned earlier would work here if you include it in the revised formulas.]

Thank again for all of your help!!

HUGE PROBLEM!

After I added and proofed the formula you created, everything was peachy on the "Selected VDOTs" tab.  So, I was wrapping up work and decided to view all the other tabs.  In doing so, I noticed that any cell that references column M from the All VDOTs tab now show "REF".  Well,  the old column where I manually keyed the Status in was column M.  Knowing that the reference got deleted when I deleted the old manual column, I simply went back into the formula and 're-referenced' column M that now has the formulas.  Rather than 'REF' displaying, '#N/A' now displays.

I spent over an hour trying to figure this out. My eyes are now crossed.  It's probably something simple for you.  But, I can't get the numbers to re-appear.

Will using the INDIRECT function help if I have to refresh the All VDOTs tab weekly?  Each week, I have to copy in a new All VDOTs tab and recalculate.  I thought of turning 'Calculate" to "manual" when I copy in the new tab each week.  But, I look to you for advice.  (I can't have this issue weekly.)
