I once again am learning Excel almost as bad as a beginner. I go through these cycles every three to five years depending on when I am working on a project; most embarrassing. I recently was reviewing some work a family member was using in his business - I asked him who did it for I was rather impressed. He couldn't recall. After a couple weeks toying with it I ran into a naming conflict. When I examined some of the names I realized I had created it about 15 years ago. I am getting old.
