I'm looking at adding a couple of slide down content features to my forum but i'm having problems, using a script from the source of this link: http://www.webdesignerwall.com/demo/...ide-panel.html

I've tried to impliment it putting some code in "header" templete and the content code in the "forumhome" templete

but it messes up the site design when doing it .. whenever ive tried to add anything with java code putting in header and forum home always messes up .. is there a way around this? or any suggestions on getting the above link working?

Thanks :)

Eddie

anyone any ideas?
