Hi @KimH,
Hmm, I just tried a test and it seems to be working fine. 0/No is selected and when I look at the source in firebug, that input has checked=""checked"" as an attribute. I copy and pasted your code block above into a radio field.
1 : Yes
0 : No
Is it possible some other javascript on the page is selecting the first one? Are you sure what you have above is what’s in the choices field. Looks like you already know this but the spaces around the colons are important.
