My boolean maths is extremely rusty but I think it is equivalent to saying: if (!($_GET['sc'] == 2 AND $_GET['sc'] == 8)) Which means your code above is *always* TRUE, so do foo is always executed! In any case you can easily test it by mentally plugging in values 1 to 8 for $_GET['sc'] and evaluating it for yourself. -- Jason Wong -> Gremlins Associates -> www.gremlins.biz Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * /* History repeats itself.
