it depends on how many buttons you have and how they are set out, (grouped),
but I have used 

if (document.form.button.value == 'on' || document.form.otherbutton.value ==
'on') {
	// fine
} else {
	// Some error routine	
	alert('please complete form');
	return false;
}

and it seems to work.  Of the top of my head I can't think of the syntax for
group of radio buttons.

If the survey is important I would see if you could use a server side
language like ASP, perl or another to verify the completion as javascript
can be disabled in all browsers and is not active in others.  That then
depends on the server you are using as to which languages you have
available.  If you have microsoft IIS and want any help on an ASP validation
routine feel free to drop me a line.

Good luck

Subject: Javascript Form Problem


I'm having to build a survey for work. I need a java script (or something) 
that will check to make sure a radio button has been checked for each 
section before the form will be accepted for submission (ie, script is tied 
to the submit button).

I've got the script for the text fields. Anyone know of one that works for
radio buttons?

all help greatly appreciated!
