Logic script - Manipulating date... Next year - 1

Dear All,

What is wrong with this code? Error message says... 01 does not exist!

What I want to achieve... get next year's YYYY from user thru prompt, subtract 1 from YYYY and then get all the base level members of YYYY.

*SELECT(%PREV_YEAR%, "YEAR", "TIME", "ID='TMVL(-12,$SEL_YEAR$.12)'")

*XDIM_MEMBERSET BUDG_TIME = "%PREV_YEAR%.01,%PREV_YEAR%.02,%PREV_YEAR%.03,%PREV_YEAR%.04,%PREV_YEAR%.05,%PREV_YEAR%.06,%PREV_YEAR%.07,%PREV_YEAR%.08,%PREV_YEAR%.09,%PREV_YEAR%.10,%PREV_YEAR%.11,%PREV_YEAR%.12"

Thanks,
Peri
