I am trying to create a formula in excel 2007 that includes a data validation cell. For example, in cell a1, I have four choices, a,b,c,d in my drop down list. In b1, I need to enter numbers that correspond to each choice in the list (I.e. a has to be between 20 and 25, b has to be between 22 and 24, c has to be between 30 and 32, d has to be between 23 and 27. if the value entered in the cell b1 is outside the desired range for the value in a1, I need b1 to turn red, but leave the original value in the cell. If it is inside the range, I want the cell to turn green. I am not sure how to make this formula. Can I use a vlookup? Or nested if statements? And, how do I address the value if false and value if true if I want my original values to remain but the cell to just turn color?

Try this: Format B1 with a fill color of Red. That will be the default for any value other than the values that fit your criteria.

Then use this Rule in Conditional Formatting, choosing a fill color of Green:

=OR(AND(A1="a",B1>=20,B1<=25),AND(A1="b",B1>=22,B1<=24),AND(A1="c",B1>=30,B1<=32),(AND(A1="d",B1>=23,B1<=27)))

Whenever that OR statement is TRUE, the cell will be Conditionally Formatted with Green.

Note: In your post you used the word "between" e.g.

"between 20 and 25". That means >20 and <25, but does not include 20 or 25. The formula I suggested has equal signs, so itwillinclude your upper and lower bounds for each letter. Remove the equal signs if you don't want them.
