Conditional formatting - equals multiple values

Hi

This must have been asked a million times before, but i can't find the answer, or the answers i thought might work didn't (XL2010).

It's quite simple, if a cell's value = 43, 56 or 99 turn blue. I want this for all of column F. (i have a lot more values but just using these as an example)

I've tried things like:
=OR(43, 56, 99)
=AND(...
and similar variations.

None of which generate an error, but the cells containing these values just remain with no fill.

Thanks

Hi Tony/TMS

Very weird.
Rule:
CELL (F1) VALUE > EQUAL TO > =OR(F1=43, F1=56, F1=99) - fill blue.

Yet as soon as i ok/apply the cell goes blue, even though it's empty. When i enter a value, be it either of the 3 values stated, or any other number, the fill disappears.
WTF?
TMS, i tried your way too, same thing.

I removed the multiple values & just used one value & it works as it should (eg if cell F1 = 2 turn blue).
Strange, any ideas?

Hi TMS

Seems obvious now.
Much appreciated.

Thanks,
Al.
