Sorry I need RegEx once or twice a year and don't know the syntax enough to help.

And if I want to test it against IDs with 3 characters I'm thinking that RegExes are the way to go. Here's what I've got that isn't quite working. var currentID:String = item.id.toString(); var pattern:RegExp = /^<currentID>/; if ( pattern.test( activeID ) ) return true; else return false; I'm thinking my pattern will test for the currentID (no matter how many characters) at the beginning of the activeID. But it's not making any matches.
