I posted the code from the attached file. In the future, please post code instead of attaching files.

Please, use proper tags when post code, traceback, output, etc. This time I have added tags for you.
See BBcode help for more info.

The file doesn't contain code to do anything other than draw the grid. If this is a tutorial, it must be first in a series.
