flash actionscript: Source Files - http://www.jmanproductions.com/Source.zip

Good afternoon,
I'm trying to recreate a Flash/ASP.net File Upload tool that I saw here:
http://www.codeproject.com/aspnet/FlashUpload.asp
This version was done with Flash 8, so I wanted to recreate it using Flash CS3
and AS3.
I was able to get the Flash 8 version working here:
http://www.jmanproductions.com/Default.aspx

So what's my problem? Well The version above uses parameters sent to the flash
player that the flash player uses for the upload method. Well I'm having
trouble pinpointing my problem with the following code. When I test it in
Visual Studio nothing happens I can't seem to figure out how to trace the value
of the parameters, which are also below the code. so if anyone could point me
in the right direction, or download the source, and help me out, I would much
appreciate it.

Thanks!

Finally. I had a co-worker of mine help me debug the problem. Apparently my
problem was not with the parameter begin brought in, because once I looked on
the server, I noticed my files had indeed uploaded. So I turned to the event
handlers. I had mistakenly assigned all the listeners to the FileRefList
object. My co-worker pointed out that the Cancel and Select ones get assigned
to the FileRefList object, and the rest get assigned to the FileRef object in
the upload function. I have pasted my latest code. Also, for all you want to
try it out, you can download the source here:

My next step will be to figure out where to add the remove listeners. My
ultimate goal will be for Flash to show the file or files in a data grid once
they are uploaded. If they are images, they will show up as thumbnails.

Thanks,
