Help with function

[Elpulpo]

I need to transform this TFS 1.x function to OTHire (7.72).

local function getMoneyAmount(position)
    local moneyAmount = 0
    for _, item in ipairs(Tile(position):getItems()) do
        local itemId = item:getId()
        if itemId == ITEM_GOLD_COIN then
            moneyAmount = moneyAmount + item.type
        elseif itemId == ITEM_PLATINUM_COIN then
            moneyAmount = moneyAmount + item.type * 100
        elseif itemId == ITEM_CRYSTAL_COIN then
            moneyAmount = moneyAmount + item.type * 10000
        end
    end

    return moneyAmount
end

It looks for the amount of money in a position and returns a variable with the amount of money.
Can anyone help me?
