What specifically is wrong in IE6 (I have’t checked yet)?
The only thing I can see wrong from a quick flick through your code is that you have two suckerfish scripts in there …
[code:1cumu3y6]
<!–[if lte IE 6]><script type="text/javascript" src="http://opensourceproject.defiant.bz/test1/wp-includes/js/ryans_suckerfish.js"></script><![endif]–> [/code:1cumu3y6]
You don’t need to include an extra one. The plugin does that for you.
If removing that doesn’t fix it then post back here and I’ll take another look for you.
