Place your ZCMD commands outside everything else - This means, don't place them in callbacks/functions.

pawn Код:

//Example
public OnPlayerSpawn( playerid )
{
   print( "hi" );
   return 1;
}

COMMAND:sayhi( playerid, params[ ] )
{
   print( "This is my first example command of ZCMD." );
   return 1;
}

Reading the ZCMD topic can give you some tips and tricks.
