    Hi Maurice,

    In situations like this, it helps if you send us the code and the
    error messages. There could be any number of things happening: the
    scripts could be getting loaded in the wrong order, there could be
    something wrong with the scripts (funny characters), there could be a
    bug in the scripts, the load command may be in the wrong place, etc.

    Again, we would need to see the script and the error messages. You
    have to be careful that you don't have duplicate versions of files in
    the same directory. For example, if you have "gsn_code.ncl" and
    "gsn_code.new.ncl", and one is a newer version of the other, you may
    run into problems because they both contain the same functions.
