Help with "OnStepOut" function TFS 0.3.6 (PoI purple fire)

[Albertum]

Hello guys, recently I started doing my own PoI fire script imitating the real Tibia one. It already increases the damage by 300 on each wrong step by the non-allowed vocations. The thing is that I'm trying to restart the counter whenever you do your first step out of fire, but I can't get to it. I guess I am not using properly the OnStepOut function, but I'll leave my script here. It's for TFS 0.3.6, Tibia client 8.6.
By the way, I make it work by using the purple fires with ID 7465, and then put in movements.xml:

<movement type="StepIn" itemid="7465" event="script" value="PurpleFireKnight.lua"/>

PurpleFireKnight.lua:

[CODE]local storage = 10199 --storing the damage counter

function onStepIn(cid, item, position, fromPosition)

    if not(isPlayer(cid) == TRUE) then
        return false
    end

    local voc = 4
    local vocpromo = 8
    local PlayerVoc = getPlayerVocation(cid)
  
    if getPlayerStorageValue(cid,storage)<1 then
        setPlayerStorageValue(cid,storage,1)
    end
                  
    if PlayerVoc ~= voc and PlayerVoc ~= vocpromo then
        doTargetCombatHealth(0, cid, COMBAT_FIREDAMAGE, -300*getPlayerStorageValue(cid,storage), -300*getPlayerStorageValue(cid,storage), 15)
        setPlayerStorageValue(cid,storage,getPlayerStorageValue(cid,storage)+1)
    else
        doTargetCombatHealth(0, cid, COMBAT_FIREDAMAGE, -300, -300, 15)  
    end

    return true
end

function onStepOut(cid, item, position, fromPosition)
      
    local aux = 0
  
    local fireTilesPos = { -- tiles with purple fire
        {x = 32830, y = 32328, z = 11},
        {x = 32830, y = 32327, z = 11},
        {x = 32830, y = 32326, z = 11},
        {x = 32830, y = 32325, z = 11},
        {x = 32830, y = 32324, z = 11},
        {x = 32830, y = 32323, z = 11},
        {x = 32830, y = 32322, z = 11},
        {x = 32830, y = 32321, z = 11},
        {x = 32829, y = 32321, z = 11},
        {x = 32828, y = 32321, z = 11},
        {x = 32827, y = 32321, z = 11}
    }

    for i=1,#fireTilesPos do
        if (getDistanceBetween(fireTilesPos[i],position) == 0) then
            aux=1
            break
        end

    end
  
    if (aux == 0) then
        setPlayerStorageValue(cid,storage,1)
    end
  
end
