Tim,

Bit of a SWAG without seeing the code in clssqpdm.prg but it's worth checking all your define class statements... make sure you don't have any lines commented out with semicolons at the end (VFP then ignores the next line even if it looks like it doesn't)

Failing that.. post the prg and we'll see if we can identify anything amiss.
