I want to add a 4 sets of polls that each have around 4 radio buttons each for answers - then i would like to add an 'enter your email address' field below these polls.

Finally I would like the submit button after the email field to 'submit' the data from the polls and the email address entered - so only one submit button.

Just to make things even better, I would like some form of validation, that will not pass the form unless all 4 polls have a radio button pressed and a valid email.

All this is then to go into a MySQL database.

I have the email validation bit nailed - so thats fine.. it's the multiple polls bit thats getting me - I cannot get it to work?! Do i have to effectively add 5 forms?

Any help would be greatly appreciated.
