Doesn't work with certain themes

So i developed a really cool form that works brilliantly using the Garland theme and Framework theme. However, when i attempt to use it on a custom theme that I wrote none of the ajax works. The form still works, it just requires lots of boring non-ajax post backs. All of the javascript and css files are included, the markup for the form itself is identical to the form rendered using Framework and Garland. The only thing that is is different is the html markup of the page and the CSS associated with the themes. Does AHAH require the theme to have certain css identifiers/markup to operate?
