[Help] Warning

[Daniels69]

Hello , lately i was making something like an house system. and i stopped at this warning. which i can't really solve , or my lua experience is too small.

it appears that the code below doesn't seem to get the housemark variable.. and that's why the warning comes , and the script doesn't really work any more , any ideas how to solve it? Thanks

CODE:

  
  
function addhouses(thePlayer,command,arg) 
    local x,y,z = getElementPosition(thePlayer) 
    local r,g,b = 255,255,0 
     housemark = createMarker ( x , y, z+1, "arrow", 1.5, r, g, b, 170 ) 
    if (housemark) then outputDebugString("house created") 
        setElementData(housemark,"mtasa-house",true) 
        setElementData(housemark,"mtasa-housename",arg) 
    --  if getElementData(house,"mtasa-housesold") == false  
end 
end 
addCommandHandler("addhouse",addhouses) 
  
function househit(player) 
      if getElementType( player ) == 'player' and not getPedOccupiedVehicle( player ) then 
   if not isGuestAccount( getPlayerAccount( player ) ) then 
     --some stuff happens here 
        else 
          outputChatBox( 'You must be logged in', player, 255, 51, 36 ); 
        end; 
      end; 
  end  
addEventHandler("onMarkerHit",housemark,househit) 

ERROR:

WARNING: Bad argument @ 'addEventHandler' [Expected element at argument 2, got nil]

[Bonus]

Use the addEventHandler when you create it (= use it after line 6).

Also you can use local for the housemarker after you did that.

Explanation:

You create the marker after using the command.

So you can't attach the addEventHandler before using the command, cause the marker isn't even created.
