SCRIPT LOGIC ERROR

HI all

i wrote the logic to multiply two accounts and moves the result into 3rd account.i have define the members correctly in the scope but when i validate getting the error as the member not def.

*XDIM_Memberset HR_Account= DRV_PENSION_TYPE_9, DRV_ANNUAL_SAL, 70036

*XDIM_Memeberset HR_Category = PLAN

*WHEN HR_Account

* is DRV_ANNUAL_SAL

*REC(FACTOR=DRV_PENSION_TYPE_9,HR_Account=70036,HR_Category = PLAN)

*ENDWHEN

*COMMIT

I am getting the error message DRV_PENSION_TYPE_9 is not def.

I have checked in the HR_Account dimension DRV_PENSION_TYPE_9 is available.

Please help..

Thanks
