Hi
Problem solved :)
I was using a formula in the first place declaring a variable and assigning a value 1 to it.
<code>whileprintingrecords;
Numbervar RH := 1;</code>
The group footer supposed to be suppressed
<code>whileprintingrecords;
Numbervar RH <> 1</code>
It was not working because the formula was placed in the page header instead of the reports header.
Now it works fine :)
