Invalid procedure call or argument

I'm in a BPC 7.5 MS dual server environment. Windows Server 2008 R2 and SQL Server 2008 R2.

I'm trying to execute a Logic task in an SSIS package. When I run it, I receive "Invalid procedure call or argument".

This is the script that is configured:

TASK(Execute formulas,USER,%USER%)

TASK(Execute formulas,APPSET,%APPSET%)

TASK(Execute formulas,APP,BUDGET)

TASK(Execute formulas,LOGICFILE,%APPPATH%\..\AdminApp\%APP%\SSISTest.lgx)

TASK(Execute formulas,RUNMODE,1)

TASK(Execute formulas,LOGICMODE,1)

TASK(Execute formulas,QUERYSCOPE,1)

TASK(Execute formulas,CHECKLCK,1)

Does anyone have any insight into what is causing this? Should I be specifying some other arguments?

Is there any more documentation concerning the SSIS Logic task beyond this?
