BI Publisher: Multiple Conditions for the Conditional Region

Hello,

I'm developing an RTF custom report with the BI Publisher Desktop. I pull information from a BP and need to show records only for several line items tabs. Thus, I used the Conditional Region to define the conditions where the line items would be shown. Out of the 5 existing tabs, I need to show the contents of only 2 of them.

Is there a way to accomplish this in the Advanced tab? Any code sample will be very helpful.

Thanks.

Edwin
