Custom data validation drop down lists

Based on the description, I think you should be able to use a pivot table to get a list of the items based on the TRUE/FALSE. Then overlay the pivot table results with a named dynamic range and use the range name for the drop-down.

Here is an article on how to make named dynamic ranges: http://www.utteraccess.com/wiki/inde...Dynamic_Ranges.

Also, if you can attach a sample workbook with non-sensitive data, we could help you out better. I will allow us to observe the issue firsthand.
