I've recently been asked to create some conditional formatting based
on a cell value. Basically what I am trying to do is have the cell
turn red if the value of a cell is outside of a range.

For example, if the value of cell F12 280 OR < 220 then I want the
cell to turn red. The standard conditional formatting has limitations
so I am left to figure out how to write a formula. Can someone assist
me with this?

Here is what I have so far but it does not seem to be working.

=IF(F12280 OR <220) then?????

Thanks in advance for your help.
