Your Inlist() function does not appear to have a closing parenthesis - did you just accidentally miss this on both lines above? FYI: Using Not should do the trick, though you sometimes need to add additional parenthesis e.g.

If Condition1 And Condition2

Would become

If Not (Condition1 And Condition2)
