iRule with two IF statements is not working correctly

I have this iRule below and it does a good job on forwarding to pools POOL_PUB_MOSS and MyCampus_Pool, but not to the Offline_Pool when all servers are down or disabled. What do I need to change?  ...

The iRule looks okay. Can you try testing again with debug logging and then check /var/log/ltm for the output? 

when HTTP_REQUEST {
   log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::host][HTTP::uri]"
   if { [matchclass [HTTP::uri] starts_with $PRODMOSS] } {
      log local0. "[IP::client_addr]:[TCP::client_port]: Matched MOSS URI check"
      if {[active_members POOL_PUB_MOSS] > 0 } {
         log local0. "[IP::client_addr]:[TCP::client_port]: MOSS pool up, using it"
         pool POOL_PUB_MOSS
      } else {
         log local0. "[IP::client_addr]:[TCP::client_port]: MOSS pool down, using offline pool"
         pool Offline_Pool
      }
   } else {
      log local0. "[IP::client_addr]:[TCP::client_port]: No match for MOSS URI check"
      if {[active_members MyCampus_Pool] > 0 } {
         pool MyCampus_Pool
         log local0. "[IP::client_addr]:[TCP::client_port]: MyCampus pool up, using it"
      } else {
         log local0. "[IP::client_addr]:[TCP::client_port]: MyCampus pool down, using offline pool"
         pool Offline_Pool
      }
   }
}
when SERVER_CONNECTED {
   log local0. "[IP::client_addr]:[TCP::client_port]: Connected to [LB::server]"
}
