jQuery and radio button validation of groups

Question

I'm hoping someone can help out with this. I modified code from jQuery and radio button groups but cannot get it to work. Here is my HTML:

Here is the jquery:

I fail the if statement in !!$(":radio[name="+group+"]:checked").length) and never set valid to true whether I chose a radio button or not.

You need to surround the selector modifier with single-quotes:

!!$(":radio[name='"+group+"']:checked").length)
