The problem is back again! My problem seemed to be solved when I went to 'Apply' and clicked on all of the range names. The Ignore Relative/Abosolute box was checked and the Use row and column names box was checked.
So now when I copy one of the formulas, the names are copied and appear in the cell as they should be. Now, if I go to edit the cell formula, the range names remain after I click into the edit window at the top. Great! But if I edit the cell formula a second time, the name disappears and I see the cell address instead.
I have Excel 2007 and I have saved my spreadsheet as a '97-2003 xls file so that I can use it at home with an older version.
Does anyone know what I am doing wrong?
