Hey Guys,

Based on this tutorial:

[http://www.kirupa.com/developer/flashcs3/preloader\_as3\_pg1.htm](http://www.kirupa.com/developer/flashcs3/preloader_as3_pg1.htm)

I’m trying to incorporate this into an older Flash piece, where the preloader works by starting on frame 1, then advancing to frame 2 once preloaded and complete. Given the above tutorial, what’s the best way to do this?

Simply adding a “gotoAndPlay(2)” in the imageLoaded function once all is said and done is throwing an error:

"  
TypeError: Error #1009: Cannot access a property or method of a null object reference.  
at loadimage\_preloader\_fla::MainTimeline/imageLoading()  
"

Any suggestions would be appreciated.

Thanks.
