CathyBryant18,
In your initial post you said you wanted to compare finish with baseline finish but that's not what your formula shows. Is the formula you are showing just an test example?
When you say it's not working, what does that mean? Is the formula showing an error (i.e. can't even get it to execute)? Does the formula execute but not give the results you expect? If so, a screen shot of a few representative tasks with the % Complete, Start, Finish, and Baseline Finish fields showing along with the custom field with your formula would help.
What field are you using for your custom formula (e.g. Text, Number, etc.)?
I did a quick check on your formula and it showed a syntax error. The second criteria showing "=>" should be ">=".
