(SOLVED) Upgrade shop not updating values?

Hello, I'm having trouble setting up my upgrade shop for the game i'm making. Im trying to make it have 4 tiers per upgrade. Keep in mind the totalUpgrades value is for unlocking the last upgrade which is achieved by buying 3 upgrades.

local replicatedStorage = game:GetService("ReplicatedStorage")
local localPlayer = game.Players.LocalPlayer
local timesBought = 0
local totalUpgrades = script.Parent.Parent.Parent.UpgradeValue.Value
if timesBought == 4 then
    print("Maxed Out!")
    script.Parent.Text = "Maxed!"
elseif timesBought == 3 then
    script.Parent.MouseButton1Click:Connect(function()
        if localPlayer.leaderstats.Coins.Value >= 1200 then
            localPlayer.PlayerData.FireDMG.Value = 45
            localPlayer.leaderstats.Coins.Value = (localPlayer.leaderstats.Coins.Value - 1200)
            timesBought = timesBought + 1
            totalUpgrades = totalUpgrades + 1
        else
            print("no money!")
        end
    end)
elseif timesBought == 2 then
    script.Parent.MouseButton1Click:Connect(function()
        if localPlayer.leaderstats.Coins.Value >= 650 then
            localPlayer.PlayerData.FireDMG.Value = 30
            localPlayer.leaderstats.Coins.Value = (localPlayer.leaderstats.Coins.Value - 650)
            script.Parent.Text = "Damage: $1200"
            timesBought = timesBought + 1
            totalUpgrades = totalUpgrades + 1
        else
            print("no money!")
        end
    end)
elseif timesBought == 1 then
    script.Parent.MouseButton1Click:Connect(function()
        if localPlayer.leaderstats.Coins.Value >= 400 then
            localPlayer.PlayerData.FireDMG.Value = 15
            localPlayer.leaderstats.Coins.Value = (localPlayer.leaderstats.Coins.Value - 400)
            script.Parent.Text = "Damage: $650"
            timesBought = timesBought + 1
            totalUpgrades = totalUpgrades + 1
        else
            print("no money!")
        end
    end)
elseif timesBought == 0 then
    script.Parent.MouseButton1Click:Connect(function()
        if localPlayer.leaderstats.Coins.Value >= 200 then
            localPlayer.PlayerData.FireDMG.Value = 5
            localPlayer.leaderstats.Coins.Value = (localPlayer.leaderstats.Coins.Value - 200)
            script.Parent.Text = "Damage: $400"
            timesBought = timesBought + 1
            totalUpgrades = totalUpgrades + 1
        else
            print("no money!")
        end
    end)
end
