I have payment submit form for USAepay

<input type="text" name="UMname" size="25" value="[UMname]">
Gets the peron's name and correctly submits it and I can see the persons name on a report at the USAepay site.

the cgi variable UMbilllname is what is used for a recurring charge.  I would like to be able to see the person's name in that report also, but I can't because the variable isn't getting set (it is a hidden ).  It has been suggested that I use javascript to acquire the value in UMname and place it in UMbillname:

function myUMname()
{
   if (document.getElementById)
   {
     var elName=document.getElementById('UMname');
     var elBillName = document.elName.value;
   }
}
</script>
</head>
<body>
<input id='UMname' type="text" name="UMname" size="25" value="[UMname]" onChange="myUMname();">
<input id='UMbilllname' type="hidden" name="UMbilllname" size="25" value="[elBillName]">
</body>
</html>

The above doesn't work and I am new to javascript, what am I doing wrong?

Instead of

var elBillName = document.elName.value;

you need to have

var elBillName = document.getElementById('UMbillname');
elBillName.value = elName.value;


However, I would recommend doing this on the server-side, if possible.

To use amit_g's solution, which is also perfectly fine, just make sure you enclose your <input> fields with <form> tags.
