>>>"IIIF()" is a function I made that returns one of the last three options. VFP is giving me a "data type mismatch" error on the IIIF line. I've used UDFs in SQL before without a problem, and I think I might have used this IIIF() before. I don't understand why it's giving me an error. IIIF.prg is in the path, so I know it can find it. And the function works on its own.

I don't know. If it bombs, so it's not very good. There are two places which can fire type mismatch: either function code itself (I hope you have very simple code inside) or SQL, when let say IIIF returns Integer (or maybe .NULL. ?) for the first record and tries to return Character for the next one.
