For one thing, your regex doesn't match any definition of "website address" that I've ever seen. Look up the spec for URLs at http://www.w3.org/Addressing/ . In the very least, you should not arbitrarily exclude valid domains just because the last part is not 2 or 3 characters - what about .info, .museum, etc.? And what's the @ for? As for your error, I'd guess it's because you wrote [0-9a-z-\.] rather than [0-9a-z\-\.] (escaping the -). miguel
