Validating Form Radio Buttongroup

[phil ashby]

Hi guys and gals,

I've got a cfform which contains radiobutton groups. I want to start the form
with nothing in the group checked, but on submission of the form, validate that
something is selected. I've tried to play with the validate param, but I'm not
having much luck. Any ideas?

Cheers
Phil

<cfinput type="radio" name="rbgroup1" value="1" label="1" checked="no">
<cfinput type="radio" name="rbgroup1" value="2" label="2" checked="no" >
<cfinput type="radio" name="rbgroup1" value="3" label="3" checked="no">
<cfinput type="radio" name="rbgroup1" value="4" label="4" checked="no">
<cfinput type="radio" name="rbgroup1" value="5" label="5" checked="no">

There may be a more elegant way to do this, but I usually use;

CFIF IsDefined('Form.rbgroup1')

Sorry, I didn't make myself very clear in my first message.

I was hoping to use the validate and validateat params and validate the form
(which will be type="flash") upon submission in the same way you can check to
see if a text box has been completed etc
