display problems

I have a password protected page that is named manager.php. Into that page I pull in a file called home.php which displays my html code. I'm trying to do an include of the index.php file for PunBB into a table within home.php.

so I'm trying to put a php file into a php file into another php file using include commands.

The manager.php is located in a directory called <test> in my root directory. home.php is in <test/_inc/>.

The PunBB index.php is located in <bb/> in my root dirctory.

This is the error msg:

Warning: main(bb/index.php): failed to open stream: No such file or directory in /home/content/a/v/8/av8ter/html/test/_inc/home.php on line 529

Warning: main(bb/index.php): failed to open stream: No such file or directory in /home/content/a/v/8/av8ter/html/test/_inc/home.php on line 529

Warning: main(): Failed opening 'bb/index.php' for inclusion (include_path='.:/usr/local/lib/php') in /home/content/a/v/8/av8ter/html/test/_inc/home.php on line 529

I've tried renaming directories paths but this does not work. Any help on getting the PunBB to work as I've mentioed would be appreciated.

Thanks,

Keith
