Hi everyone,

I’m trying to send a dynamic textbox instance name as a parameter, so I can use it in a function.

e.g.

btn\_play.addEventListener(MouseEvent.MOUSE\_DOWN, playVideo);

function playVideo(event.MouseEvent):void{  
updateText(txt\_inputbox);  
}

function updateText(textboxName:string):void{  
textboxName.text = “Hello World”  
}

Is this actually possible if so what parameter type do I set textboxName as?  
I cannot use the event.currentTarget as the function is called after clicking on a different button.

Any help would be much appreciated.  
Thanks in advance.
