Vote for the best Car Ever

This page demonstrates how you can use the DISABLED tag in the submit area. By using the DISABLED tag, the user will not be able to click the submit button until all the information on the form has been entered.
You can use the DISABLED tag in any of the form's elements, but it makes the most sense to put it in the SUBMIT section.

McLaren F1 (ALT-m)
Ferrari F550 Maranello (ALT-f)
TVR Tuscan "Speed 12" (ALT-t)
Porsche 911 Turbo"R" (ALT-p)
All of them (Please don't make me choose... They're all insane autos) (ALT-a)

A script will be necessary to enable the submit button, once the choices have been made.
