Yes, the error occurs here (when the page loads). I think I've solve the problem by changing: var model_id = event.target().value; to: var model_id = $('form_model_id').value; In this function: function model_id_changed(event) { var model_id = event.target().value; var def = doSimpleXMLHttpRequest("/model/" + model_id + "/ get_lab"); def.addCallback(replace_lab); }; The javascript on the page was mostly taken from <<http:// docs.turbogears.org/1.0/RoughDocs/dynamicform>>, so I'm actually a little over my head here. Now I have a function, model_id_changed, that isn't using it's argument!
