Hi,
  Did you remember to run "pkg_mkIndex ." in the directory containing
exmp.tcl to create the necessary pkgIndex.tcl file? Before you try
adding it to the VMD menu with vmd_install_extension you'll want to
make sure that it correctly autoloads when you run the command:
  package require exmp

Once that works, I would expect your script to work from the GUI as well
assuming there are no other problems. (The code below looked fine in
my very quick examination..)
