I have a load issue with my video player since I added a timer and RED play progess bar to it. It plays perfectly by itself here:

[http://www.playingthepoet.com/FlashAPI/AnimaliaPlayer.swf](http://www.playingthepoet.com/FlashAPI/AnimaliaPlayer.swf)

BUT it is supposed to load into the API here:

[http://www.playingthepoet.com/](http://www.playingthepoet.com/)

Please click on “Animalia - Verse From The Zoo”. The .swf still loads but the video is not playing. The blue load progress and the red play progress, timer and video are not engaging. I added the red play progress and timer functions to what I had previously built via a video player I found here:

[http://www.thetechlabs.com/tutorials/audionvideo/how-to-build-a-as3-videoplayer/](http://www.thetechlabs.com/tutorials/audionvideo/how-to-build-a-as3-videoplayer/)

When I test locally, loading the Video Player .swf into the parent API .swf, (and click on “Animalia”) I get an error message that says:“TypeError: Error #1009: Cannot access a property or method of a null object reference.  
at ScrubbingPlayer2\_fla::MainTimeline/initVideoPlayer()  
at ScrubbingPlayer2\_fla::MainTimeline/frame1()  
removing animalia  
Im looking for [object Loader] and I am [object MainTimeline]  
[object Loader]  
TypeError: Error #1009: Cannot access a property or method of a null object reference.  
at ScrubbingPlayer2\_fla::MainTimeline/unloadThisSkin()”

So it’s a problem concerning how the

“initVideoPlayer()”

function cannot talk to the parent API.

Do I need some kind of parent and child Dispatch Method to resolve this? As I learn AS3, I’m finding the most complex problems are load issues between parent and loadee .swf files. And this is another one. I’ve attached all the code for the Video Player, and the relevant loading code from the parent API below. My question is this: How do I code the parent and loadee .swfs to make the video play WHEN IT LOADS INTO THE PARENT API just as it plays by itself on the above first URL? Phew!! Sorry if that’s over-worded but just trying to be clear. Many thanks. WF
