One option is to produce a set of helper columns, so from "T 2" in F9 you
could extract the 2 by =RIGHT(F9), and copy across appropriately. Use the
new columns in your SUM (and hide the new columns if you want to).

Hello,

I'm a new user to excel and forumlas. I have a column that has a total
number of units in C9. In column C8 are names of people. I have to
either
put next to the names T 2, T 4, E 2 or E4 (F9 to AD9). I am using the
following formula to subtract from the total number of units for each day
in
the month.

Formula in Cell AE9: =(C9-(SUM(F9:AD9))/2)

This works perfectly for me when I only insert number 2 or 4. In column
AE,it gives me the number of UNUSED UNITs.

Well now my boss wants me to enter the letter T or E with the NUMBERS, and
I
don't know how to adjust this forumla to IGNORE the letter so that the
formula continues to work. Right now when I add a letter to the cell, the
formula ignores the number.

I hope this makes sense as I'm desperate for a solution. I have digged
through a bunch of help sites, but I'm not technical enough to understand.

Thank you for your help!
