The javascript functionality theForm.submit() doesn't work in Netscape and Firefox.
E.g. in your example code, if you create a link on the page to submit the form using the following href: "BLOCKED SCRIPTdocument.theForm.submit()" the information entered into the cute edit control does not get submitted to the next )page (if you use a button of type "submit", it does work.
It does however work in Internet Explorer.
