If my question is off this group, please point me in the right
direction.

Here goes:

My scipt fails between alert-2 and alert-3 with

"Object doesn't support this property or method" (freely translated
from Danish).

Any idea what could be wrong?

The code is a rip-off from
http://xaprb.com/articles/number-formatting-demo.html.

<script language="javascript" type="text/javascript" >

function fNr(context){
alert("1");
var val = (context == null) ? new Number(this) : Math.abs(this);
alert("2");
var arr = val.round(2).toFixed(2).split(',');
alert("3");
arr[0] = (val < 0 ? '-' : '') + String.leftPad((val < 0 ?
arr[0].substring(1) : arr[0]), 1, '0');
alert("4");
arr[0] = Number.addSeparators(arr[0]);
alert("5");
arr[0] = Number.injectIntoFormat(arr[0].reverse(), '0###',
true).reverse();
alert("6");
arr[1] = Number.injectIntoFormat(arr[1], '00', false);
alert("7");
return arr.join(',');
}

</script>

In the context of your ripped-off version, "this" is the HTML document. In
the context of the script you ripped off, "this" is a JavaScript object,
specifically, the JavaScript Number object:

http://www.comptechdoc.org/independent/web/cgi/javamanual/javanumber.html

The author of the script has extended the Number object via prototyping.The
following tutorial should help you to understand how it works:
