Improving someone's code

Don't call your submit button 'submit' if you want to change the submit event with Javascript:

If you do, the browser (please read “Firefox 1.5 or IE 6? - that’s what I tested at the moment) will consider submit is an object. And an object is not a function (although you might enjoy later on the paradox that a function is an object).
