Take it from someone who went Ga-Ga in School over Boolean Math - Parentheses change everything. Try A and B or C and D versus (A and B) or (C and D). Stuff in Parenthesis is always evaluated first. I tend to use lots of them 'cause I'm still confused by AND/OR precidence and get even more confused when you throw in a NOT. Consider A or B and C or NOT D. <Hair starts to come out>.

If it is, I didn't see it in that chapter! Doesn't that rule apply to expressions inside parentheses? - Dan __________________________________________________ Do you Yahoo!? Yahoo!
