Error 1046 out of the ordinary

Hey all, i’m currently receiving a weird error, and i think I know why. but have no idea how to solve it, wondering if anyone would shed any light on this situation.

I have a framework im using, which has a preloader which passes flashvars into the main swf once loaded, I then call an external class which adds elements to the stage and aligns them.

The items have the linkage set, to app.display.[mc name], this was working completely until i added the function from the preloader to call the function in the main doc class.

I think the linkage is incorrect as everything was perfect before I called the function from the preloader.

This bug is confusing and annoying, but i think it’s something simple that once you know you never forget.

Thanks
