Javascript and Regex

[Super Dave 26]

var raw = '{1}';
var matches = raw.match(/\(?(\d{3})\)?[- ]?(\d{3})[- ]?(\d{4})/g);
if ( matches != null) {
alert(matches[0]);
}

 

I'm trying to match a phone number in many formats. I've worked very hard to figure that regex out and tested it with different sandboxes

Ubot throws an error that doesn't give much explanation, just the text from my code (shown above). Anyone able to shed some light on this?

what kind of error does it throw?
