Hi there,

I have a problem when using variable in expression. I want to count AccountID with vVari  is null conditional.

This is my code, but it not work

Count({<AccountID={"=$(vVari)='-'"}>} AccountID)

Thanks for your help !

May be this

Count({<AccountID={"=Len(Trim($(vVari))) = 0"}>} AccountID)
