Training problem

[ScorpiOOn93]

Hello.
I have a training movement script that if player stand on some tile it will crete 2 training monks and it's working, but i think that function "DoCreateMonster()" is bugged because when some player throw a FIRE BOMB or something like that on tile when it should create a training monk it will send a error:

 [14/10/2009 15:39:50] Lua Script Error: [MoveEvents Interface] 
[14/10/2009 15:39:50] data/movements/scripts/train.lua:onStepIn

[14/10/2009 15:39:50] luaDoCreateMonster(). Cannot create monster: Paladin Trainer

and it will not create a training monk :/

Can someone tell how to fix that or edit this script for something like if player leave the training room it will remove the fire fields etc.

Script:

 function onStepOut(cid, item, toPosition, fromPosition)

local trainers = {
	["Sorcerer Trainer"] = 1,
	["Druid Trainer"] = 2,
	["Paladin Trainer"] = 3,
	["Knight Trainer"] = 4
}
local trainers2 = {
	["Sorcerer Trainer"] = 5,
	["Druid Trainer"] = 6,
	["Paladin Trainer"] = 7,
	["Knight Trainer"] = 8
}


local positions = {
	[4000] = { {x = toPosition.x-1, y = toPosition.y-1, z = toPosition.z, stackpos = 253}, {x = toPosition.x+1, y = toPosition.y-1, z = toPosition.z, stackpos = 253} }, -- North
	[4001] = { {x = toPosition.x-1, y = toPosition.y+1, z = toPosition.z, stackpos = 253}, {x = toPosition.x+1, y = toPosition.y+1, z = toPosition.z, stackpos = 253} }, -- South
	[4002] = { {x = toPosition.x+1, y = toPosition.y-1, z = toPosition.z, stackpos = 253}, {x = toPosition.x+1, y = toPosition.y+1, z = toPosition.z, stackpos = 253} }, -- East
	[4003] = { {x = toPosition.x-1, y = toPosition.y-1, z = toPosition.z, stackpos = 253}, {x = toPosition.x-1, y = toPosition.y+1, z = toPosition.z, stackpos = 253} }  -- West
}


if getPlayerPromotionLevel(cid) == 0 then
 for trainer, vocation in pairs(trainers) do
				if getPlayerVocation(cid) == vocation then
					for action, position in pairs(positions) do
						if isPlayer(getThingfromPos(getCreaturePosition(cid)).uid) == TRUE then
							if item.actionid == action then

      rem = getThingfromPos(position[1])
      rem2 = getThingfromPos(position[2])
      doRemoveCreature(rem.uid)
      doRemoveCreature(rem2.uid)
       break
       end
      end
     end
    end
 end
elseif getPlayerPromotionLevel(cid) == 1 then
for trainer, vocation in pairs(trainers2) do
				if getPlayerVocation(cid) == vocation then
					for action, position in pairs(positions) do
						if isPlayer(getThingfromPos(getCreaturePosition(cid)).uid) == TRUE then

      rem = getThingfromPos(position[1])
      rem2 = getThingfromPos(position[2])
      doRemoveCreature(rem.uid)
      doRemoveCreature(rem2.uid)
      break
      end
     end
    end
   end
 end
end
return TRUE
end
