Flash forms

Hi, Ive just edited a Flash template bought by my client which includes 2 forms -estimatesandemail contact`.

My problem is that I dont know how to make the forms dynamic. What actionScript should I attach to thesendbutton (movieClip)? I know that I need to use PHP as well but this is new to me. Ive seen tutorials but they seem to differ from each other.

Can anyone suggest some simple code to use so the user can send info to my client`s email address ?
