Okay... I'm thinking somethings not getting extended somewhere... var el = $($(this._relative).id); alert(el); //object alert(el.parentNode.parentNode); //object alert(el.up()); //ie: object doesnt support this property or method //ff: object alert(el.up(1)); //ie: never gets called //ff: Error: Selector.findElement is not a function, Source File: prototype.js Line <http://localhost:1694/Listz/Javascript/prototype.js Line>: 1435 Gareth
