Formula not working for conditional formatting in Excel

Question

I'm trying to setup a formula for a conditional format.

Here's what I want to do:

For any row in column D that has a value different than the same row in column C, highlight the value in Row D

Some of the values are text so I only want this formula to work for values that are numeric.

This is the formula I came up with:

=ISNUMBER(AND($D2:$D1308,$D2<>$C2))

Unfortunately, it's not working. I'm not sure where I went wrong. Any suggestions are appreciated.

Thank you!

Answer 1

Try this:

=AND(ISNUMBER($D2),$D2<>$C2)
