Code goes between brackets.

pawn Код:

public callback(params)
{
  //code goes here
}

so you need to find OnGameModeInit, and put the object lines inbetween the brackets:

pawn Код:

public OnGameModeInit()
{
  // then other code can go above/below yours.

  // all your objects go here

  // then other code can go above/below yours.
}
