On change, with bindings

I’ve got this sweet app that will give me a photogallery essentually, but for some reason, the data of my list component will only trace. And when i try to put it into a load movie agrument, it doesnt work, i get this message:
Error opening URL “file:///<path_to_folder>/[object Object]”;

anyway, if you dont get what i mean, take a look at this

form.change = function(eventObj){
container.loadMovie(eventObj.target.value);
trace("Value changed to " + eventObj.target.value);
}
myList.addEventListener(“change”, form);

the trace always pops up a valid path to a picture. but i get that error opening… with my file system on it. Whats that about?
