Using variables in a expression

[gabriele]

Hello.

I have a problem using a variable in an expression.

I have the variable "v_date" = insert by user (for example = today() )

Then other two variables "v_Range_Offer" = (v_date - DataOffer) and "v_Range_Confirm" = (v_date - DataConfirm) .

I must do the profiling of clients, like this in the other variable "v_Profiling":

if(
( isnull( aggr(count( {$< v_Range_Offer={">0 <=1825"} >} [Offerta Seriale]) , [Cliente.Seriale] ) ) ) and
( isnull( aggr(count( {$< v_Range_Confirm={">0 <=1825"} >} [Pratica Seriale]) , [Cliente.Seriale] ) ) ), 'A.Suspect',

if(
( aggr(count( {$< v_Range_Offer={">0 <=730"} >} [Offerta Seriale]) , [Cliente.Seriale] )>=1 ) and
( isnull( aggr(count( {$< v_Range_Confirm={">0 <=730"} , [Tipo]={"P", "PO"} >} [Pratica Seriale]) , [Cliente.Seriale] )) ),

'B.Prospect', 'Z.Other'))

This don't work, neither with the expansion $ in the variable.

Any suggestion?

Thank you, Gabriele.
