_Please_, when showing the output, show it as it is, without
editing.  There is no way this is what really appeared on
your screen.  (The second line shouldn't have the <root...>
bit at the beginning.)  Your transcript obscures the problem,
rather than illustrating it.

> <root at localhost>export TEST
> <root at localhost>echo %TEST
> <root at localhost>set
> <root at localhost>./changetest.sh

You need to do 

   $ . ./changetest.sh
     ^

The . command runs the script in the current shell, without
forking a new process to run it.

Later,
