It looks as though something might be going wrong in the AGI script itself.  
Did you use a "proper" AGI library, or a quick-and-dirty homebrew solution?  
(There is little virtue in walking all the way to the tool shed to fetch a 
chisel, if you know the screwdriver you already have in your drawer can be 
used for the job.  On the other hand, breaking your screwdriver by 
inappropriately using it as a chisel does not look too good either.  Knowing 
the difference is one of the qualities of a great programmer.)

SET VARIABLE is a legitimate enough command, but ****** probably is not a 
valid variable name.  Maybe there was a forbidden character in there before 
you redacted it?

I would try to isolate the problem, by writing an AGI script that *just* sets 
a variable to some fixed value and exits; and having a corresponding extension 
that *just* calls the AGI script, displays the variable's value in the CLI 
with a NoOp() statement and then hangs up.  When you know you can do that, and 
successfully read back the value from within your dialplan, *then* you can 
make it decide what value to put in that variable.
