currency . Value - amount?

I made a script that when a player touches the door, the house becomes theirs and lets say 75 dollars is deducted from the players money. I suck at scripting, and this doesnt work i need help....

things to know -- the leaderstats script is located in workspace

local debounce = false
local player =  game.Players.LocalPlayer
local money = game.Workspace.Leaderstats('Money')
local amount = script.Parent.Parent.Price
function onTouch(hit)
if hit == nil then return end
if hit.Parent == nil then return end
if not game.Workspace:FindFirstChild("Home"..hit.Parent.Name) then
if game.Players:findFirstChild(hit.Parent.Name) ~= nil and debounce == false then
debounce = true
local b = script.Parent.Parent:Clone()
b.Parent = game.Lighting
b.Name = "Home"..hit.Parent.Name
wait(.4)
script.Parent.Parent.Ay.Value = hit.Parent.Name
if money >= amount then
    money.Value = money.Value - amount
end
script.Parent.Head:Remove()
script.Parent.Parent["Home: Nobody"].Name = "Home: "..hit.Parent.Name
script.Parent.Parent.Parent.Name = "Home"..hit.Parent.Name
end
else
end
wait(3)
debounce = false
end

script.Parent.Head.Touched:connect(onTouch)
