Hi,
I need to count how many items in the report have a particular string.
I'm using:

[SUM(<frxDBdataset."Confez"> = 'Pronto')]

The result is correct (35), but is negative!

eg -35.

How can it happen?

thanx
miyomo

    the sum function is for numeric values
    use count function
    see the user manual on aggregate functions.

    sorry my mistake, you can use the sum function with a condition but you need the band name.
    of the band where the datafield originally appears.
    ie

    [SUM(<Customers."Country">= 'US',Band4)]
