Newbie NN4 help...

Hi people... I've just used PHP for the first time... It's being used as a CSS-style switcher (my client didn't want to use a javascript client-side solution)... I have it all working well in most browsers I've tried it in.... EXCEPT the dreaded NN4* ... This script uses a cookie... And then switches the styles... Is there something I don't know about that would cause NN4 to be unable to use this? I'm rather at a loss and my site is two days over deadline... :( If anyone could point me in the right direction I'd be VERY appreciative... The page I'm playing with is here: http://www.kspope.com/phpswitch/test6.php The switcher is at the bottom of the page... And it reloads the NN page, but doesn't change it. (Don't mind the NN "mess" I"m working on the styling for that browser right now)... Thank in advance for any input... :) Stephanie Sullivan VioletSky Design http://www.violetsky.net ³I am always doing that which I can not do, in order that I may learn how to do it." -Picasso
