Hi Stew

Select Cells C10:E10, then apply your conditional format.
The conditional format should work on all these cells. If not, pls post back

Happy New Year to all

This Formula in conditional format only works in Respect to C10.

I am trying to achieve that if a number is placed in any of these cells
the
conditional format is true

=ISNUMBER(C10:E10)

What is my mistake

Best
