Hi all,
I've written a small script to allow the user to enter a telephone number (like 0690-HELP) and it would convert it to the numeric equivalent (ie. 0690-4357). But i've got a problem with the javascript giving me a message saying one of my form objects "is null or not an object".
I've included the code below and if anyone could be so kind as to assist i'd really appreciate it!
=====================================================
<html>
<head>
<script type="text/javascript">
<!--
function noNumbers(e)
{
var keynum
var keychar
var numcheck
if(window.event) // IE
{
keynum = e.keyCode
}
else if(e.which) // Netscape/Firefox/Opera
{
keynum = e.which
}
keychar = String.fromCharCode(keynum)
var parsed_number = "";
numcheck = /\d/
if(!numcheck.test(keychar))
{
keychar = keychar.toUpperCase();
if((keychar == "A") || (keychar == "B") || (keychar == "C"))
{
parsed_number = 2;
}
else if((keychar == "D") || (keychar == "E") || (keychar == "F"))
{
parsed_number = 3;
}
else if((keychar == "G") || (keychar == "H") || (keychar == "I"))
{
parsed_number = 4;
}
else if((keychar == "J") || (keychar == "K") || (keychar == "L"))
{
parsed_number = 5;
}
else if((keychar == "M") || (keychar == "N") || (keychar == "O"))
{
parsed_number = 6;
}
else if((keychar == "P") || (keychar == "Q") || (keychar == "R")|| (keychar == "S"))
{
parsed_number = 7;
}
else if((keychar == "T") || (keychar == "U") || (keychar == "V"))
{
parsed_number = 8;
}
else if((keychar == "W") || (keychar == "X") || (keychar == "Y")|| (keychar == "Z"))
{
parsed_number = 9;
}
document.Form1.txtConvert.value += parsed_number;
}
else
{
document.Form1.txtConvert.value += parsed_number;
}
}
//-->
</script>
</head>
<body>
<form id="Form1">
<input type="text" name="txtNumber" onkeypress="return noNumbers(event)" />
<input type="text" name="txtConvert" />
</form>
</body>
</html>
====================================================
Any assistance is appreciated!

Change <form id="Form1"> to <form name="Form1"> or if you want leave the id and just add the name="Form1". It shouldn't hurt either way. Hope this helps.

Also just noticed, you have a typo in your code.
You have:
document.Form1.txtConvert.value += parsed_number;
twice. The second one (the one in the else) should read:
document.Form1.txtConvert.value += keychar;
Fix these things and the script will work.
