Maybe I'm missing something simple, but how do you get group headers to only print for their respective group. For example, I have 4 groups and wish to only have them print when a field in the data is equal to the group number.

I have set up the group expressions as

data.flag = 1
data.flag = 2
data.flag = 3
data.flag = 4

and have it set to start a new page with each group, but:

on page 1 the headers for group 1 and 2 print.
On page 2: group 1 and 2
page 3: 1,2 and 3
page 4: 1,2,3 and 4

What do I have set wrong, or do I have to use a single group and use "print when"?

TIA,
