Your second button doesn't work because it is a Flash button and it's quite complicated to get Flash/swf files embedded in web pages to communicate with HTML aspects of the page.
My recommendation would be to create an image of the button that you want to use (eg. jpg or gif) and then use the first lot of code. If you are using Dreamweaver it is relatively straightforward to use an image as a button in a form.
Hope that helps :)
