Help with Do Loop Correct order of events

I need to determine the OverrideAmount Paid by comparing the Previous Years value to the quarterly event.

See ee post:  http://www.experts-exchange.com/Database/MS_Access/Q_28384010.html
for the first part of the equation.  works great, however per the  problem below  I have to loop thru 2 recordsets.

I need to first determine the quarter , then retrieve a value from each of the 6 fields for that quarter and compare that value against a previous years value that is also stored in the table for each quarter.

the following is the field names not the field value.

Tier           1       2         3        4         5        6           PrYr
Qtr1      Q1T1, Q1T2, Q1T3,Q1T4, Q1T5, Q1T6         .385
Qtr2      Q2T1, Q2T2, Q2T3.Q2T4, Q2T5, Q2T6          1.25
Qtr3      Q3T1, Q3T2, Q3T3,Q3T4, Q3T5, Q3T6          .774
Qtr4      Q4T1, Q4T2, Q4T3,Q4T4, Q4T5, Q4T6          .333

if Qtr1 = Q1T1 = 0.44 Q1T2 = .50, Q1T3 = 1.45, Q1T4 = 3.00, Q1T5 = .25, Q1T6 = 6.0

So I need to be able to set the value of

PrYR = .385 and compare against the value of the 1st qtr for each tier for Qtr1.

Then go to Qtr2 and repeat the process but grap the Q2 PRYR value = 1.25 and compare against all Tiers for Qtr2.

As so forth for each quarter.

then I need to compare the value of the PrYr and if it is the following then

If PctYrlyIncrease< Tier1 Pct (Q1T1) Payout = ‘0’
elseIf PctYrlyIncrease> Tier1 Pct (Q1T1) and < Q1T2 then
Sum(TotalNetUSExp * T1E)
ElseIf PctYrlyIncrease> Tier2 Pct (Q1T2) and < Q1T3 then
Sum( TotalNetUSExp * T2E)

and repeat for each Tier per Each Qtr.

Here is my code so far:
if .34 <  Q1T1 (.1)  then = nOvramt = 0

.34 > .1 but < Q1T2 (.50) THEN  novramt = Sum( TotalNetUSExp * T2E)

cont to compare the .34 value against each Q1T??? until equation = true.

             If True then increment Q?T1, etc.

Your problem stems from not having a normalized table.  Any consideration of normalizing that table?

Year  Quarter    Tier   ValueField
2012      1            1             x
2012      1            2             x

This structure would make it significantly easier to do this type of comparison.

Do the values in this matrix reflect sales performance, or something like that?  If so, you might want to actually use 6 columns to represent this:

Year  Quarter    Tier      MinVal     MaxVal     Multiplier
2014      1            1            .44            .50              
2014      1            2            .50           1.45
2014      1            3          1.45           3.00

Where multiplier is the value you are multiplying by the value TotalNetUSExp (T1E, T2E, ...)

Then to get the Multiplier you would simply use a query or a DLookup within that table for the record where the value you are testing for falls between the Min and Max values (actually >=MinVal AND < MaxVal)

where did the .34 value come from?  I thought you were using .385 in your example.

where did the .34 value come from?  

It was just an example I used not an actual value, then I went back an reposted the actual values.


Unforunately, this is the way the data is, it comes from a datawarehouse.  I inherited the data   The entire mdb is not normalizated, not referential intregity.  a real mess, but I not here to fix the issues just create a report based on existing data.

Got any ideas on how to loop thru the data to get the results.

Where multiplier is the value you are multiplying by the value TotalNetUSExp (T1E, T2E, ...)

these are additional fields within the same table.  The Q?T? fields contain a percentage that I need to compare to the previous years percentage(PY).  and if PY is compared until the Q?T? value is greater than the PY for that quarter - to return an dollar amount based on the above mention equation.

Normalization, How would you go about accomplishing this task?

I had this thought last night.

I under an extreme deadline I only have 1.5 weeks left on this assignment.  I could really use your help.
