I have set up a conditional format that will change the color of a cell
when
a value changes higher or lower from the previous cell in the column. My
problem is that I am using a lettering system which goes (A+, A, A-, B+,
B,
B-, C+, C, C-, D+, D, D-, E+, E, E-), but the spreadsheet sorts these
letters
in this fashion (A+, A-, A, B+, B-, B, etc....). Can someone tell me how
I
can change the automatic sorting??? Thanks for your time.
