Thanks so much for your insights. The code you propose makes sense, but whenI run it with my form, it doesn't seem to actally get any of the answers provided. I created the @fiels array using the names that I use in the form (i.e. 'name','01','02','03' etc....). In my form, I have about 20 different elements that are radio button choices, so for question 2 it might be something like:

     <input type="radio" name="02" value="a">

            Required in my major </td>

          <td> 

            <input type="radio" name="02" value="b">

            Required, not in my major </td>

          <td> 

            <input type="radio" name="02" value="c">

            An Elective </td>

When the user picks the third option (value="c"), then I want that to show up for the value of field (name) "02". If they don't choose any of the options, then it will be a comma. When I test the code you suggest, I get a comma for every answer, whether I selected anything or not. Any ideas? I really appreciate all the information as I wade through this.
