i had to do something similiar like this. Here's what I did.
PHP Code:
function onTimeOut() {
Master_Gui_Text_Account.setText ( "Account : " @ player.account);
Message_Board.width = Message_Window.width-25;
}
I'm not sure if this is what your asking for but, it might help.
Also, they might not be the most efficent but they work great for me.
