Compiler error. Report to NI Tech Support: ufppushop err, c=0xF1

Compiler error. Report to NI Tech Support: ufppushop err, c=0xF1 When saving/runing a vi that performs some calculations in a formula node containing several if's and a switch statement. (LV6.1, WinNT)

Re: Compiler error. Report to NI Tech Support: ufppushop err, c=0xF1

I've solved the problem: the compiler error occurred because one input of the formula node was an enum. When inserting a cast to numeric, the problem was solved.
