Hi delic, What Adam said. Also, it seems you are using Mootools also, so you will want to look into jQuery's noConflict() function once you have the core jQuery file loading. This will allow you to use both libraries at the same time - although you would be best off doing everything with jQuery and get rid of Mootools completely ;)
