I have the same problem, I have a series of data that requires addition,
however, some cells contain the letter "C" which must equal to 60. The
formula Pete_UK provided in this thread worked wonderful.

However, now that I have the columns added, I have to divide the total by 60
to reach the total number of hours instead of minutes. How do I add that
division calculation to that formula?

Can anyone help me?

Thank you

Here's an array* formula that should do it:

=SUM(IF(A1:A20="X",10,A1:A20))

Adjust the range to suit - I have assumed numbers in A1:A20.

* As this is an array formula, then once you have typed it in (or
subsequently amend it) you need to commit it with CTRL-SHIFT-ENTER
(CSE) instead of the usual ENTER. If you do this correctly then Excel
will put curly braces { } around the formula when viewed in the
formula bar - you must not type these yourself.

Upper or lower case X will be treated as having a value of 10.

Hope this helps.

I need to be able to put a letter, X into a cell which would then, when the
row was added, the X would count as 10. The X needs to remain in the cell,
and not just simply change to 10.
However I still need to be able to return a value in to the same cell, such
as 1, 2, 3, etc if I dont want to use the letter X.

Hope some one can help and thanks in advance!
