One thing to watch out for in Biff's formulas... if your entries are not
well controlled, there is a remote possibility of getting false hits. For
example, if your user enters MarMay in AK2, the that cell will turn blue. As
structured, if your user types in any substring from "JANMARMAYJULSEPNOV"
(such as the MarMay I used) or from "FEBAPRJUNAUGOCTDEC", then those
substrings will be considered a hit.

Use the Formula Is option and use these formulas:

For Blue:

=AND($AK$2<"",SEARCH($AK$2,"JANMARMAYJULSEPNOV"))

For Green:

=AND($AK$2<"",SEARCH($AK$2,"FEBAPRJUNAUGOCTDEC"))

I am trying to make a conditional formatting formula in cell A3 that goes
something like this =$AK$2=JAN, MAR, MAY, JUL, SEP, NOV to format Blue
and
=$AK$2=FEB, APR, JUN, AUG, OCT, DEC to format Green. It keeps coming up
with
"You may not use unions, intersections or array constants for conditional
formatting criteria. Cell A3 and cell AK2 both have array fomulas. Is
there a
solution to make this work?
