First Radio button in loop...

[eluser]wakey[/eluser]
Hi,

I have a feeling I may be missing something obvious here, but my situation is this -

I'm using a loop to echo through some database entries and adding a radio button next to each one using the form helper. I want the first entry or at least one of the entries to be selected by default.

Is there any easy way to do this?

Cheers,
W
