PowerCMS & User Registration System

Let me explain my setup.

PowerCMS: configured and setup one site with CMS and all the pages the CMS controls.

User Registration Sys: configured and setup another site within dreamweaver with this system. Used my own layout etc. Both systems work fine alone. Now I must combine the two as the site PowerCMS is controlling is also the site that requires user's to be registered to access the content. And each page within that site has a sidebar that draws something from PowerCMS.

I combined all the files into one site (or folder) on my testing server and also updated any paths in the config files for PowerCMS or URS (none of the files had the same name so this was no problem combining).

Originally I got an error saying "users.contents" does not exist, this was pasting the DB connection info for PowerCMS at the very top of say users_Registration.php - I then tried to export the CMS database into the user management database, updated cms config, didn't work. Changed the databases back to each having their own.

I then inserted the DB connection info for CMS just above the "head" tag & below all the stuff the user management system inserts into the header of your template & it seems to be working fine. Do I have this configured properly or is something going to go weird later on?

Is there any better way of doing what I'm trying to do? Combining the databases into one etc. or anything? Thank you.
