Creating a form help

Hey all, I’m just looking through the “Creating a Form Using Components” tutorial and I’m wondering if someone can help me out a bit. What I’m trying to create is a domain searching form and I’m using radio buttons for the first time. Basically, I want it to read the things in the text and radio buttons and go to a .php search link

Here’s the link to what I’m trying to create:
