This form contains a variety of features including field-by-field data verification, help menus, individual field resetting, as well as the usual submit and reset funcitons. Image links are used for buttons as opposed to <input> buttons.
Try adding a full name without a space in it or an email address without a "@" or "." to test the error control.
Note: This data is not actually sent to a database. It is used only to generate a JavaScript alert() box. In actual practice, your submit button would ultimately lead to a CGI program of some sort that would install the data in a database on the server.
