I am probably missing something simple here, but the following code seems pretty clear and is not working:
<html>
<head>
<title>Untitled</title>
</head>
<script type="text/javascript">
function popuplateTotal() {
var quantity = document.forms["register"].elements["txtQuantity1"].value;
var cost = document.forms["register"].elements["txtCost1"].value;
document.forms["register"].elements["txtTotalCost1"].value = quantity * cost;
}
</script>
<body>
<form name="register">
<input type="text" name="txtQuantity1">
<br>
<input type="text" name="txtCost1" onChange="populateTotal();">
<br>
<input type="text" name="txtTotalCost1">
</form>
</body>
</html>
<html>
<head>
<title>Untitled</title>
</head>
<script type="text/javascript">
function popuplateTotal() {
var quantity = document.forms["register"].elements["txtQuantity1"].value;
var cost = document.forms["register"].elements["txtCost1"].value;
document.forms["register"].elements["txtTotalCost1"].value = quantity * cost;
}
</script>
<body>
<form name="register">
<input type="text" name="txtQuantity1">
<br>
<input type="text" name="txtCost1" onChange="populateTotal();">
<br>
<input type="text" name="txtTotalCost1">
</form>
</body>
</html>

Perhaps looking at the error would give it away: "populateTotal is not defined" - which it is not.
You are calling a function with a different name to the one kaht provided you with.

I had a MTG tournament that night and my head wasn't exactly in my work.....
I lost the first round 1-2, but subsequent rounds looked like this: 2-0, 2-0, 2-0.
I ended up in 4th place, not too bad after being out for about 4 years.
