Properties/CHMOD

Hello, I searched through most of the archive to look for a simple answer to my problem to find no solution...

I've tried to change access to my files like the tutor program told me.

Hi-lighting the object, then going to Properties/CHMOD, Changing the Permission to 777 for access pressing ok, then it comes up with the following message:

500 'SITE CHMOD 777 CanArticles': command not understood.

what am I doing wrong???

thank you beforehand for the help...
Alex

chmod is not supported by your remote server.
