A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Have you mannually entered the data validation list or are you using a list located elsewhere in your workbook?
Is the spelling correct in the resource (data validation or list)? Are there any spaces you're not seeing?
If you're using a list - I would add the Index function to the formula.
If you would send me the workbook - I can take a look.
