Hey guys i am really new to PHP and programming in general. I am trying to build my own web form that can dynamically show different fields based on the selection made before it. I just dont wan the user to hit 'SUBMIT' five times just to finish the form completely. I am sure there is some sort of AJAX or JS to help with this but the problem is..... i have no idea what im looking for

FML im such a noob and would love if you guys could help a greenhorn coder out. I have taken a look at a lot of the scripts this site has to offer which is freaking awersom!! but i have no idea how to utilize those lol so any help is appreciated guys, thanks in advance!
