I need to be able to write a macro in one database that will run a macro in another database.

The current action I am trying to use is RunApp. I have a similar macro for excel and the command line is EXCEL.exe I:\OTI\Mi_Accts \Cost_Provision s\Mirror_Tables \MACRO_HOLDER.x ls. I thought it would be as simple as changing it to access.exe I:\OTI\Mi_Accts \Cost_Provision s\Mirror_Tables \Master\OA Provisions by Month.mdb but it did not work....
