[JASS] I don't get it

This trigger dosn't work. The game runs, but this trigger which runs on map initialization fails for some reason:

function Trig_Remind_Actions takes nothing returns nothing
  local integer i

  loop
      exitwhen i == 4
      if GetPlayerController(Player(i)) == MAP_CONTROL_USER and udg_DecisionMaker == Player(15) then
          set udg_DecisionMaker = Player(i)
      elseif GetPlayerController(Player(i)) == MAP_CONTROL_NONE then
          set udg_PlayerScore[i] = -1
      endif
      set i = i + 1
  endloop
  call DisplayTimedTextToForce(GetPlayersAll(), 20.00, (GetPlayerName(udg_DecisionMaker) + ", type \"-time #\" in a chat message to set the game time in minutes."))
  call DisplayTimedTextToForce(GetPlayersAll(), 20.00, "Enter \"-time 0\" for no time limit.")
endfunction

Please define what it is meant to do, since otherwise it is not easy for people to help.

You need to initialize i to 0

(local integer i = 0)

What's nothing + 1? I don't know, and I'm sure the computer doesn't either.

Yes, that was the problem, thanks.
