Radio Button Question/Problem???

[Guest_imported]

I understand how to iterate through a set of radio buttons to get the value for the one selected by using something like this:
for (i = 0; i < document.formname.radiogroup.length; i++)

However, on IE 5.0, if you have only one radio button in the group, this technique appears to break. The value I get returned for the radiongroup.length is undefined?? Has anyone else seen this strange behavior, and if so, is there a work around?

Yes. I've seen this too. A workaround:
if(document.formname.radiogroup.length)
for (i = 0; i < document.formname.radiogroup.length; i++) [sig]<p>nick bulka<br><a href=mailto: > </a><br><a href=

Thanks,

I did manage to use the elements array of the form object to get the same value, though I will try your suggestion.
