You are quite right about the HTML never noticed that thanks!

Removing the jscript_jquery-1.5.min.js makes no difference apart from breaking the slider.

Removing http://ajax.googleapis.com/ajax/libs.../jquery.min.js from cookieControl-5.1.min.php and adding jscript_jquery-1.5.min.js back into the jscript folder allows the slider to work but no cookie control.
