Data Validation

Copper Contributor


I have created a form in excel where I have used data validation to create drop down lists. I also want to apply data validation to some of these cells to not allow the cells to be filled in if an answer to a previous question is “no”. I’ve tried lots of formulas but can’t get it to work! Can this be done?

Could you attach a small sample workbook demonstrating the problem (without sensitive data), or if that is not possible, make it available through OneDrive, Google Drive, Dropbox or similar?


You could create a copy of the original validation list with the formula

= IF(replyQ1="yes", optionsQ2, "None")

and that becomes your new validation list (it must be a range and not simply an in-memory array).
