length property not being captured
<p>I know I have to be doing something dumb here. Just need a second set of eyes. </p>

<p>Validating if my radio box has been checked:</p>

<pre><code>&lt;input type="radio" name="cont_amt" id="cont_amt" value="1000"&gt;

  //alert(theForm.cont_amt.value);
  var con_optLength = theForm.cont_amt.length;
  var chkd="";

  for(var i = 0; i &lt; con_optLength; i++) {
        if(theForm.cont_amt[i].checked) {
            chkd=theForm.cont_amt[i].value;
        }
  }


if ( chkd == "" ) {
      reason += "\t" + "Must select a contribution option" + "\n";
  }
</code></pre>

<p>I'm always hitting my alert because my <code>length</code> is always undefined.</p>
