Can’t move focus to control?
So like me you spent 30 minutes trying to fix this Internet Explorer JavaScript error ?
Cant move focus to the control because its invisible , not enabled, or a type that does not accept the focus.
In that case don’t waste time trying to understand it, odds are you have conflicting ids in your document. Also, remember IE 7 and the previous versions are alone to think a name attribute should be treated like an id.
