Hi, I'm helping a friend with Excel. She has a spreadsheet that we set up with the first column being the date. I formatted the cell as "general" for her so that she could put in the month and day, then only the day in the following rows, (e.g.. first column Oct 10, second row 11, and so on until November). The problem is that she keeps calling me telling me that when you puts the, say 11 in it resorts back and inserts Jan 11. I keep going back and reformatting the cells to take as "general" and it works find. Then when she closes out and comes back to it later, all the formatting has changed back. I have protected the worksheets, but unprotect to make the changes, then protect again after I finish. I also highlight the entire column to do the formatting to insure the entire column is included. One more bit of info, there are several identical sheets she is using, and I change EACH one, then only some don't take, or resort back. What am I doing wrong? This is the blind leading the blind.....Thanks!
