Formula in Excel 2003

  Abel 12:34 10 Feb 2007

Doubtless there's a simple answer to this problem, but it's one I'm unable to fathom. In Microsoft Excel 2003, how do you sum non adjoining cells? I've tried, say =A3+A7+etc (which works in Lotus 123) but 'value' is returned in the cell. When I hover the cursor over little box, with an exclamation mark in it, at the side of the cell it says 'A value used in the formula is of the wrong data type',
Thanks in advance for you advice.

=SUM(A3,A7,G4) If this doesn't work you may have to format one or all the cells as numbers as they may be listed as text.

It only works Chocolate Cake! It's simple when you know how! Thanks for the very prompt response.

Sounds like there's something odd with some of the cells you are trying to sum. The formula you've included there should give you the sum of cells a3 plus a7 etc.

The strange part about the problem Silverous, is that some cells with the formula I included in my post were not flagged by the system as problematical, whereas others were. However, having used Chocolate Cake's solution, the problems in all cells went away.

You can always use e.g.


to ensure that any numbers entered as text are treated as numbers.

Thanks VoG™. I think that was the problem; the plus sign was probably being read as text in a number field. Anyhow, all is now OK, but I shall bear your suggestion in mind for the future.
