When you say the send button doesn't work, what happens? Do you get a javascript error, does anything get printed to the screen, does the page reload?
Usually, things like this are caused by javascript conflicts on the page. If you're using Firebug, you can check for JS errors before and after you hit the "Send" button and let us know what happens. If you'd like us to debug it further, include your website address so we can look into it.
