Hi,
I want to use Data Validation in a form. I have already defined names with the columns I want to show in the Class dropdown (E9) when Category dropdown (E8) is selected. E9 also needed to be a Multi Select dropdown.
I tried to use INDIRECT and IF...LOOKUP in Data Validation, but returned with error.
Please help me to solve this problem. The file I'm attaching is a lot smaller than the actual one. Would that be too big to use Data Validation?
Thanks for the help.
