Help developing a RegularexpressionValidator for a numeric field

[amazononthemoon]

Help, I am wanting to use a RegularExpressionValidator on a webform to only
allow a numeric value with 2 decimal points. I want to make it flexible so
the user can enter commas and numbers. ie 1,000.00 or $1000.00 or 1000.00 or
$1,000.00. The user should also be able to enter 10,000.00 or 100,000.00 or
10,000,000.00. If someone has one they use I would like to copy it

Thanks in advance for your help

You can use the CompareValidator instead and set Type="Currency" and Operator="DataTypeCheck".
