How Do I Pass a Value from a Scriplet Variable to an iReport Parameter?

I wrote a scriptlet that executes an Oracle SQL function called "get_bps_rept_gn". It returns a number that I am trying to pass to an iReport 3.5.1 parameter. The parameter is called $P{bps_rept_gn}. Whenever I try to pass the value to this parameter, the parameter displays as null. I can successfully pass the value to a variable of the same name as the parameter ($V{bps_rept_gn}. This value displays in the report. I'm new to scriplets so I may be missing something in the syntax.
