Sounds like you have a missing reference.
Look under Tools, References and see if any are missing.

I have a Microsoft Excel application which uses API calls to open the
dialog box to select a file. For some reason when this API is run in
XP it doesn't work. Now, simple functions like String(x,y) and CurDir
no longer work.

Does anyone know how to fix this?

Thanks!
