Variable for radio buttons?

[Cheech]

Hi

I am calling this function with chkQ("document.responses.q1") and my form has a set of radio buttons named q1. The for loop runs the correct number of times but the var rad_val is always undefined?

function chkQ (id) {
	for (var i=0; i < id.length; i++)
	   {
		   
	   if (id[i].checked)
		  {
		  var rad_val = id[i].value;
		  }
	   }
	alert("Q1 value = " + rad_val);
}

Anyone able to spot what I have got wrong?

Hi

chkQ("document.responses.q1")

That way you are passing one string, so the loop steps over its characters.
