Supress detail line if fields are zero 1

[matahari]

I have a problem supressing a Group Footer line if the a field in my Group Footer line is zero. Here's what I did:

In the FORMAT SECTION for the Group Footer - I added the following formula in the formula editor on the Suppress (No Drill-Down) line (I have the Suppress check box unchecked):

GroupNumber > {?Top N} //This condition works ok
or
(Sum ({@Total Variance PRD}) = 0.0) //Can't get this condition to work

Try this in the same formula editor.

If SummarizedField = 0
Then True
Else False
