Follow what Rob suggested to get the US currency to work. Once you add the \. it works as desired. This regex-coach program allows you the enter a reg exp and test it on test input. It has some issues, but it is free. http://weitz.de/files/regex-coach.exe

just a nit but instead of . use \. so you match only the literal instead any one character; at least inside VB/ASP .NET (subject to your 'local' currency format settings)
