I simply forgot to include the table tags. However, the 2nd and 3rd radio buttons are still not directly under the 1st radio button. I'd like to have them vertically aligned (in a column).
I also altered your table structure slightly, if you try the posted markup you'll see it works, getting the "Input type:" header to vertically align to the top of the list is left as a trivial, please do some of the work yourself, exercise;)
