Hi!

I tried your code, and it outputs the correct HTML:

<input type="radio" name="complete" value="1" />Yes
<input type="radio" name="complete" value="0" />No
<input type="radio" name="complete" value="-1" />N/A
[download]

I splitted the output in 3 lines for readability. There 0 is there, does it show this way to you? If it does, the problem probably lies elsewhere, i.e. where you process the submitted form.
