I needhelpwith assigning a point light/material change to a part once a stat value is reached. Help?

Here is my code currently, sorry if it is messy but I am really getting fed up as I have tried so many different things but the code refuses to acknowledge the Cash value

local config = script.Parent.Config
local Lighting = game:GetService("Lighting")
local Part = Instance.new("Part")
local pointlight = Part:FindFirstChild("PointLight")
script.Parent.Part.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChildOfClass("Humanoid") then
        local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
        if plr:FindFirstChild("leaderstats") and plr:FindFirstChild("Cash") then
            local leaderstats = plr:FindFirstChild('leaderstats')
            if leaderstats then
                if leaderstats.Cash.Value >= config.Cost.Value then 
                    leaderstats.Cash.Value -= config.Cost.Value
                    if plr.leaderstats.Alpha.Value < 1  then
                        leaderstats.AlphaBeta.Value = (leaderstats.Beta.Value * 1.2)
                        leaderstats.Multiplier.Value += (config.Amount.Value * leaderstats.AlphaBeta.Value)
                    end
                    if leaderstats.Alpha.Value >= 1 and leaderstats.Beta.Value >= 1 then
                        leaderstats.AlphaBeta.Value = (leaderstats.Beta.Value * 1.2) * (leaderstats.Alpha.Value * 2.5)
                        leaderstats.Multiplier.Value += (config.Amount.Value * leaderstats.AlphaBeta.Value)
                    end
                    if leaderstats.Alpha.Value < 1 and leaderstats.Beta.Value < 1 then
                        leaderstats.AlphaBeta.Value = 1
                        leaderstats.Multiplier.Value = leaderstats.Multiplier.Value + (config.Amount.Value * leaderstats.AlphaBeta.Value)
                    end
                    if leaderstats.Beta.Value < 1  then
                        leaderstats.AlphaBeta.Value = (leaderstats.Alpha.Value * 2.5)
                        leaderstats.Multiplier.Value += (config.Amount.Value * leaderstats.AlphaBeta.Value)
                    end
                    while wait() do
                        if game.Players.LocalPlayer.leaderstats.Cash.Value < 1000 then
                            wait(0.1)
                            Part.Material = Enum.Material.Plastic
                            pointlight.Enabled = false

                        elseif game.Players.LocalPlayer.leaderstats.Cash.Value >= 1000 then
                            wait(0.1)
                            Part.Material = Enum.Material.Neon
                            pointlight.Enabled = true
                        end
                    end
                end
            end
        end
    end
end)

script.Parent.Part.GUI.TextLabel.Text = "L"..config.Cost.Value.." = x"..config.Amount.Value
