I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can try following regular expressions.

Example if you want to validate $2000 you can use

^\$\d+$  or if you want to validate $3000.00 then use

^\$\d+\.\d{2}$ or if you want to validate a negative then use

^\-\$\d+$

or a parenthesis then add ^\(\$\d+\)$ .

Though there is a library for regular expressions which you can use it to tailor with your needs.

Hope this helps

I don't need a negative, but I do want to used commas.
Guru JiCommented:
The following will do the commas too

^\$?([0-9]{1,3},([0-9]{3},)*[0-9]{3}|[0-9]+)(.[0-9][0-9])?$

It will match any of the following numbers with or without comma

$3,023,123.34 OR 9,876,453 OR 123456.78
