PHP Understood!

I finally figured out PHP. The main issue I kept having was being unable to get any text to appear at all. Using the php command inside Terminal really helped find a few simple syntax errors I could detect without it. I didn't realize how loose php was for a scripting language and that it was literally embedded into code. My php code previously was before the entire html document so nothing would show up and I would only be able to see the text through terminal. The second solution I had to a problem was changing the value of each radio button. Previously I had them as the age range but then it occurred that I could just store them like an array with 0,1,2 for the values.
