I have a workbook with many worksheets. Each worksheet has validation lists in some of the cells, with the arrow that pops up when the cell has focus. I have run into a wierd problem where the validation is not working, even though I went in verified that it is set up correctly. I have also tried creating a new one, and while it is set up right, it still does not work. I click on cell, and nothing happens. But I have other sheets in the workbook that are working fine and have the same set up. Is there some kind of setting that turns off validation in a sheet?
