Loader problems

I have been trying endlessly to find a solution for a problem. All I want to do is to be able to load a loader container on to the stage and swap out each swf by hitting the corresponding btn. I found a code to do this and it works on static swfs but when I link xml photogallery swfs to it I get all kinds of output errors but the functions work in a browser. I know it is the code as I have tried 4 different kinds of xml photo galleries and all return similar output errors.

I know this is a bit of a pain in the @#$ but if someone could have a look at the zip file in the link below which contains a main.swf, an swf folder and one swf inside including all the xml. You will see what I mean. What I really need to accomplish is to have a set AS3 code for doing this, I’m sure a seasoned AS3 pro could look at the code in the file and see why I get the errors or I’ll even settle for a code that works. I’m the kind of person that likes to know why something doesn’t work and when it works I like to know how as well. This is one of the reasons I’ve been knocking myself out for days as you will see posts of mine about this. Learning AS3 the hard way on trial and error has it’s good points as I know alot more now than I did a week ago, but I could really use some help here.

zip file link is here
