[gradsusr] Hello to all users of Grads

[avi kojokro]

First I work with Windows, and the version of Grads 2.0.a9, I'm pretty new
to Grads.
I have a problem with this script, is not working and I do not understand
what my mistake,I'd love if someone will help me.
Attaching the script and screenshot of Grads and the error it registers to
me.

Avi.
