Ah, I knew there was some sort of object oriented thing I just wasn't 
getting. I will give that a try.

Yeah, I'm hardcoding (or I was). Unfortunately, I'm not using Flash, 
I'm using Viewlet Builder (which outputs .swf) and I wanted to have the 
last frame of my viewlet go to the next viewlet, and figured I could do 
that by passing a query string to some html in-between page saying 
which viewlet is asking for the next. Needless to say, it didn't work.

So, in the process of attempting to do this, I was trying to figure out 
some sort of workaround with Flash as a wrapper, but ran up against the 
same problem and couldn't figure out why. LoadVars wouldn't even work. 
I knew there was some stupid mistake I must be making. And there's the 
answer: not asking the LoadVars object to send _root objects, but to 
send its own. We'll see if that really works. Sometimes I don't 
understand the quirks of Flash 2004. It doesn't always behave the way 
the help files says it should.

Anyway, I ended up solving my original problem using frames to maintain 
state. At least now I may have something else to try for a future 
project.
