We have an Excel 2003 worksheet that someone outside of our company created. When I'm in some cells, a box appears next to the cell that states "Calculated Cell Do not enter data in this cell". I cannot for the life of me determine how this "help box" (as I like to call it) was created or how to edit it or delete it from being associated with these cells. It doesn't appear to be a comment, as I can't delete it. I have right clicked both the cell and the box it to try to edit, delete or change, but I don't get anywhere. Does anyone have any idea on how this was created? We've tried to contact the created of this document but haven't had any response to that either.
