I'm looking for a macro that executes when I open my spreadsheet. I need it to create a list of my tab names that I can use as my data validation drop down list. I have found that if I have a range name containing the tab names, I can use it in my data validation list (for example typeing in "=tabnames" in the list range of the data validation selection. I would prefer to have the list residing in my range names as opposed to on a sheet somewhere. Any advice is welcome.
