Actionscript 3 error "1120: Access of undefined property replay"

[kidd6441]

VERY new to Flash.

I wanted to insert a simple replay button at the end of a flash animation. The button name and instance name is "replay", and this is the AS3 code I'm using:

stop();

replay.addEventListener(MouseEvent.CLICK, onClick);

function onClick(event:MouseEvent):void
{
gotoAndPlay(1);
}

When I try to test it I get this error:

1120: Access of undefined property replay.

What am I doing wrong? Thanks.

do you have a movie clip called replay with instance name replay?

tr8er8, thanks but I figured out the problem-- I needed to have the button exist throughout the whole timeline of the animation, that was all.
