Frame Label not found

Question

I have an FLA with two scenes. The first scene is an
opening...at the end it goes to the next scene called Main.
On Main I have a series of buttons....that click to different
frame labels in Main.
When I play JUST the scene it works fine...but when it goes
from the opening into Main...I get this error on all the buttons:
ArgumentError: Error #2109: Frame label Board not found in
scene Main.
at flash.display::MovieClip/gotoAndPlay()
at ASIS4_fla::MainTimeline/onMouseClickBoard()
There is a label called Board...and it works with that scene
alone...any idea why it doesn't work when coming off the previous
scene.
Thank you in advance...

Answer 1

this is on the first frame of the scene...when I do test
Scene...it works great. But Test Movie I get that error
btn_boardcert.addEventListener(MouseEvent.CLICK,
onMouseClickBoard);
function onMouseClickBoard(event:MouseEvent):void
gotoAndPlay("Board");
