Hi.
I have a IIF statement to generate a status field on my fastreport page.
Status: [(IIF(<frxDBDatasetTemp."paga_liqu"> - SUM(<frxDBDatasetBapa."bapa_liqu">,DetailData1,)>100,'true','false'))]
On execution it acuses Unknown variable on the field frxDBDatasetTemp."paga_liqu".
The problem is that I can show the value of this field with no problem. The problem seems to happen only when I try to calculate or compare the value of the field.
Thank you for your time. Cheers.

    Did you build this expression using frs expression builder or
    did you just type it in the memo view?
    I assume you have the memo in the correct footer

    I tried both ways.
    Could it be inside the wrong footer even if I can print its value with no problem?
    The problem only happens when I try to make calculations on it.

    in which event are you trying to make calculations?
    the IIF function is for use in a memo and the sumfunction is for use in amemo
    in a footer

    IIF((value - sum) >100,'true', 'false')
    The calculation is inside the if statement. I've tried this before and it seems to work great for other type of data.
