Here's a better mask to use:
<var>
<var-name>mask</var-name>
<var-value>^\$?\d+(,\d{3})*(\.\d{2})?$</var-value>
</var>
This mask:
--allows (but does not require) a leading dollar sign (if you want to remove
this feature, get rid of the "\$?" at the beginning (but leave the "^")
--allows (but does not require) a decimal point + 2 trailing digits.
It requires:
--each comma to have at least 1 digit before it (fails on ",500")
--exactly three digits after each comma (fails on "$1,00.00")
Here's a tester you can put in your HTML:
<script>
var pattern = /^\$?\d+(,\d{3})*(\.\d{2})?$/;
if (pattern.exec("$1,500,200.99")) {
alert ('matches');
} else {
alert ('does not match');
}
</script>

Subject: Re: Validating an amount with commas allowed
I'm useless with regex. However, I found this on the web some time ago and
seemed to match what I needed back then:
<var>
<var-name>mask</var-name>
<var-value>^(?:\d+|\d{1,3}(?:,\d{3})*)(?:\.\d{1,2}){0,1}$</var-value>
</var>
This allows them to include the ".00" if they so desire.
