Select C2:C100, or whichever of the 2 ranges you want the format to change
on.

Formatconditional formattingformula is
=C2F2

then select whatever formatting you want

I am trying to use conditional formatting comparing one range of cells to
another range. For example - C2:C100 compared to F2:F100 respectively -
I am wanting to format the cell to tell me if C2 F2 and C3 F3 and so
on.
I can't seem to figure it out.

Thanks,
Peggy
