I've reposted it--give it another try now. In the code for each radio button, there was no "value" set. I added "value = 1" "value = 2" etc. to the appropriate options and now the values write to the data file.

And yes, you can alter the look of the HTML in any way you like. At worst, you can always go back to the original but in general, formatting will not affect the functionality.
