I created a worksheet that contained cells with drop-downs created via
data/validation using a named list. The list resides on another sheet in the
same workbook.The users did something to make the drop downs disappear and
now I cannot reestablish them. I have done this numerous times and cannot
figure out why I cannot do it now. I checked to assure I have the required
Add-ins, so that's not the problem. Can there be a setting somewhere that is
preventing it? Help!
