Going Crazy, loader, simple file example included

[mgason]

Hi,
I am using the bulkloader class which I was directed to on this board.
It is really good, but is proving beyond my AS3 knowledge.
It can be found here
http://code.google.com/p/bulk-loader/

I have attached a zip file with everything needed to look at my problem in its simplest form.
basic_shell.fla includes the class basic_bulk.as
this loads partA.swf and partB.swf in sequence.
It displays percent loaded of the total for both files in a textbox.
This much works fine

There is a button in partA.swf that should load partC.swf, does not work.
The textbox in basic shell should display the percent loaded for partC.swf, does not work

NOTE All the loading is handled in basic_bulk.as
I have not been able to get this working in the basic_bulk.as
My last attempt is commented out in the .as file.
All the files are in fla form, just export swf's.
all class files are included in the correct folder setup.

I am in over my head!
I have stripped this down to absolutely basic, so hopefully someone will take pity and take a look.

thanks
mark
