You're trying to use a Lan server menu which isn't going to work..


From the IVPBot manual..

Running POD-Bot on Win32 Dedicated servers:

Install POD-Bot as described above and create a game the way you normally would.
When running a dedicated server the POD-Bot commands that are normally
available in the client console are disabled. To create a bot you
must set the CVAR "pb" to the command you desire.. To use the "pb" CVAR you
would use one of the following commands on the dedicated server command line...

pb "addbot"
pb "addbot 100 5"
pb "addbot 20 1 DumbAss"

In addition these commands are supported:
pb "fillserver 5" (Fills server with auto-assigned Bots)
pb "fillserver 1" (Fills server with Terrorist Bots)
pb "fillserver 2" (Fills server with Counter Bots)
pb "removebots" (Disconnects all Bots from the Game)
pb "killbots" (Kills all Bots in the current round)
pb "newmap mapname" (Changes the Map)

etc etc check the manual.
