Lua Please help with levers and walkable levers Dog racing mini game.

[Nyarl666]

Hi. I wanted to do a Dog Racing like in the original Tibia. But I don't do well with these coal basins. That when the dog steps on the walkable lever, the coal basin lights up, and when it comes out of it, it goes out. I also have a problem with the levers. They work but I had to use two levers because I can't make the stalagmites disappear on one.
Please help.
I use TFS 1.4.
For walkable levers I dont have script.
This is script for levers and stalagmites:

local config = {
    wall_id = (386),
    pos_wall = Position(948, 1009, 9),
}

 
function onUse(player, item, fromPosition, itemEx, toPosition, isHotkey)
    local tile = Tile(config.pos_wall)
    if tile then
        local stone = tile:getItemById(config.wall_id)
        if stone then
        stone:remove()
        config.pos_wall:sendMagicEffect(CONST_ME_POFF)
        player:sendTextMessage(MESSAGE_INFO_DESCR, "START!!!")
        Item(item.uid):transform(1946)
    else
        Game.createItem(config.wall_id, 1, config.pos_wall)
        config.pos_wall:sendMagicEffect(CONST_ME_TELEPORT)
        player:sendTextMessage(MESSAGE_INFO_DESCR, "CLOSED CAGE...")
        Item(item.uid):transform(1945)
        end
    end
    return true
end
