Hi Shirlene,

Which version of ReportBuilder are you currently using? We had an issue
similar to this one for some versions of RB 9. If you have not already, I
would suggest updating your version of ReportBuilder to 9.03 or higher.

Hi Nico,
Thanks for replying. I'm actually "still" using RB7.04. We are unable
to upgrade at the moment for other reasons.
