How to Make This door take Cash away and save when bought?

So someone helped me with this door but It does not save on rejoin and it does not take away the Cash or (Sips) Can you help me make it save and MOSTLY Take away cash?

local _M = require(script.Parent.Settings)

script.Parent.Touched:Connect(function(hit)
    local plr = game.Players:GetPlayerFromCharacter(hit.Parent)

    if plr then
        local rebirths = plr.leaderstats.Sips

        if rebirths.Value >= _M.RequiredSips then
            script.Parent.CanCollide = false
            wait(.5)
            script.Parent.CanCollide = true
        end

2nd script if you need it

local module = {
