I have completely uninstalled the 1.3.1.1 Mambo-SMF integration, and reinstalled the new 1.3.1.2 version; however, I still have the same problem when I click on "Forum" from the Mambo menuitem list:

Notice: Constant SMF already defined in C:\Documents and Settings\rdelacruz\My Documents\Web\rgvoffroad\healthcaretechies\forum\index.php on line 38

This appears at the top of the forum page, even though the forum appears to work correctly.  This error gives visitors to the site an uneasy feeling about something being unreliable.  I would very much like to get rid of this, but don't know how.

If anyone can help me, it would be greatly appreciated.

I uninstalled the SMF package and reinstalled.  The screen indicated it was successful after I clicked proceed.  Also, each one of the elments indicated a successful install:
1. Execute Modification ./index.php Success
2. Execute Modification ./Themes/default/script.js Success
3. Execute Modification ./Sources/Post.php Success
4. Execute Modification ./Sources/Subs-Post.php Success
5. Execute Modification ./Sources/Profile.php Success
6. Execute Modification ./Sources/Subs.php Success
7. Execute Modification ./Sources/LogInOut.php Success
8. Execute Modification ./Sources/QueryString.php Success

The error still appears, though.

I thought I already resolved this errors showing up on the SMF error reporting. What version are you using?

Cowboy! Thanks a bunch for fixing the error with your most recent patch update 1.3.1.3!!!!
