Problems with including the index page of roundcube

[paritycheck]

Hi guys,

I'm trying to include the index page of roundcube in a php page in a parent directory but its not working I keep getting a database not connecting error. This happens only when I try to include the index file in a parent directory of the roundcube mail folder.. if I include the index.php file in another file within the same folder the roundmail program it runs liek a charm?

Please what am I missing out here - what changes do I have to make to get this to run perfectly when included in a file in a folder anterior/parent to the roundcube mail folder... ?
