I was trying to do this in a SQL Q but thought it would be easier to do multiple calculations in my form if I used Calculated Controls instead.
I have a table Lookup_Tbl_Fiscal_Year with Start_Date, End_Date and FSA_FY.
In my form I want to take the date entered in Last_Signature_Date and look up the FSA_FY. The Last_Signature_Date would fall somewhere between the Start & End dates.
Here is what I got but no matter what date I enter I get 0 back.
=Nz(DLookUp "[FSA_FY]","[Lookup_Tbl_Fiscal_Year]","[Last_Signature_Date]">="[Start_Date]" And "[Last_Signature_Date]"<="[End_Date]"),0)
I read that this might slow down the system. Is it better to use SQL?
