Need help with modules

I need to have 7 separate modules exactly like Sections, but each having a
different name.

My first attempt was to find/replace every instance of Sections in the
Sections module, but although the module initializes and activates, when I
try to get into it, I get an error:

Fatal error: Call to a member function on a non-object in
/home/web/www/members/modules/air/index.php on line 84

Obviously, this module I named Air. I've been through the Envolution docs
and now I could use some help. If someone could at least point me in the
right direction to solving this, I would appreciate it.

Thanks,
Stretchr
