Yeah, good point - that's another way to do it. And I guess that could turn out to be easier over all depending on what the custom page is like. If it's basically the same as the error page but with more or different text, then that seems like it would be much easier.

I'm not that advanced, if you could guide me it would be appreciated.

Under "Plugins & Products", select "Add New Plugin"
Next to "Hook Location", find "error_nopermission"
For "Title" enter something so you'll know what it is later, like "Guest No Permission Redirect" or whatever you want.
Paste the code in the big text box.
Select "Yes" next to "Plugin Active"
Save

If you want to disable it later, you can just go to "Plugin Manager" and uncheck the "Active" checkbox and save. (Or delete it completely if you want).

You really should read that part of the manual if you get a chance, it's not really very long.
