Excel msg User-defined type not defined - but no VB code
I have an Excel spreadsheet with several tabs and vlookups. It also, at one time, included a VBA macro which I used to populate columns on the spreadsheet. The macro has been removed, and no macros remain.
However, whenever I change any cell on the spreadsheet, I get the "User-defined type not defined" error message, which is extremely annoying.
Why am I getting this error and how can I resolve it?\
