Help With: Error #1009: Cannot access a property or method of a null object reference

Hey guys, I really need your help on this one. I feel that it could be a simple solution, but my knowledge of Flash is not that extensive yet!

Ok, before I tell you my problem I can show you pretty much exactly what I am up to. I am trying to re-build a website that is pretty much identical to this one: www.ariza.com.tr/

By you checking that website out, will probably help in understanding and answering my question.

Ok, so, like in the website that was provided in the link, I have constructed all of the graphics necessary for the circle rig which is used to navigate most of the site. I just got done animating the rotation for both the outer circle ring with the first section of buttons on it, and one of the inner circle rings that appears when one of the outer buttons is pressed.

I animated the rotations + scaling through the use of motion tweens.

I created this entire circle rig in its own movie clip that I am in turn dropping into the main timeline on a single frame.

I wrote a line of code for a button on the outer ring of the circle rig to activate one of the inner circles to appear/scale/and rotate with the various sub-categorized buttons, like in the above linked website. I am achieving this animation because it has already been pre-made, through the use of motion tweens. I am simply using the button to tell the playhead to jump ahead (gotoAndPlay) through the use of labels, to play that section of the timeline, in turn animating my rig on the click of a button.

This is my error message:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at lary_web_fla::CircleRigIntro_3/frame1()[lary_web_fla.CircleRigIntro_3::frame1:1]

This is appearing in the output section. Keep in mind that I am running this animation inside of its own movieclip and then dropping it onto the main timeline.

Here is the code that I input to the actions panel that triggered that error message:

outer_ring.film_btn.addEventListener(MouseEvent.CL ICK, loadFilm);

function loadFilm(e:MouseEvent):void {
gotoAndPlay(“film_ring”)
}

Please guys I really need your help on this one! I can’t figure it out!!
If you need anymore information that could possibly help you in helping me, I’d be more than happy to post it.
