Problem with set analysis

[geogou1973]

Hello.

I have the following expression

=Sum({<SALES_DATE={'$(PREVIOUS_UDATE)'},FORMAT={'FRANC'},SALES_YEAR=,SALES_MONTH=>}AMOUNT_TRIG)+

Sum({<SALES_DATE={'$(PREVIOUS_UDATE)'},FORMAT={'HYPFL','SUPER','PROXI','CASHC','HYPMI'}-{'FRANC'},SALES_YEAR=,SALES_MONTH=>}SALES_AMT_FPA)

In this expression i have the sales for the previous day for format FRANC from the field AMOUNT_TRIG plus the sales the the previous day for the other formats except FRANC from the field SALES_AMT_FPA.

In this expression if i choose another format from the multi box i haven't the sales for the FORMAT i have choosen.

How can i have the same results like the expression give me but when i choose another FORMAT having the data for the choice i have done ?

Can anyone help me with this ?

Thank you in advance.

If you want to choose the FORMAT from a multibox then don't hard-code it in the set analysis expression. Just remove FORMAT={'FRANC'}, and make sure that a value is selection in the multibox. Or create a variable that will make sure either FRANC or the selected value is used:

    vFormat: =If(GetSelectedCount(FORMAT)=1,FORMAT, 'FRANC')`

You can then use FORMAT={'$(vFormat)'} in your set analysis expression.
