Question by Charles B: How do i use PHP/AJAX to update my form with new questions based on answers given to existing questions?
I am trying to write a form in PHP, my problem is here…when I ask if someone is over 18 and they answer yes, I want nothing to happen, but when they answer no, I want a new question to show up that asks if they have parental consent. I was told I could use AJAX to do this, but I cant for the life of me figure out how to do it.

If they answer under 18, unhide the span with the parental consent question. You don’t need AJAX for that, just plain old-fashioned Javascript will do it..
