Reverse Lookup Problem

[Idris Saliu]

Hello All,
  I'm a DNS newbie, trying to setup reverse lookup for a couple of 
domains. Reverse lookups work fine from within my network, my name 
server, but i get error messages when I do the same lookup else where. 
I have attached some files here, maybe the guru's here will see what 
I'm doing wrong put me through. Thanks in advance.
