Templates in Sub-folders Can't read Session Vbls.??

["Spitfiresix"]

I just placed a sub folder in my site that contains a separate ap, a CF chat 
board. Trying to integrate the chat board log in with my primary site log in, I 
cannot get pages within the chat board to read session variables that were set 
during the user's primary site log in. ????? What the heck have I forgotten???
