This has me completely stumped!

Why doesn't this conditional formatting get applied?

The formula is correct. I've put the same formula in column O (adjusted for
the column offset) and as you can see, evaluates to TRUE.

That highlighted 23 is also conditionally formatted. Just a test to make
sure that *any* CF is working.

Thanks
