Infinite 'End' glitch. Expected ')' got 'end' ?

Hey, I've tried adding 'end to fix it, I've also tried to put () but nothing seems to work. Any tips?

The last 'end' is errored with this: https://imgur.com/a/iqCZvTV

local productId1 = 976013381 -- 15
local productId2 = 976013480   -- 50
local productId3 = 976016228	-- 150
local player = game.Players.LocalPlayer

script.Parent.MouseButton1Click:Connect(function()
if game.Players.LocalPlayer.leaderstats.Stage.Value == 111 then -- change number to stage
    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId3) -- make Id2 the id of the diff cost
else
if game.Players.LocalPlayer.leaderstats.Stage.Value >= 51 then -- change the number to the stage
    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId2)
else
if game.Players.LocalPlayer.leaderstats.Stage.Value <= 49 then -- change the number to the stage
    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId1)
end
end
end
end)


script.Parent.MouseButton1Click:Connect(function()

if game.Players.LocalPlayer.leaderstats.Stage.Value == 10 then -- change number to stage
    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId2) -- make Id2 the id of the diff cost
else
if game.Players.LocalPlayer.leaderstats.Stage.Value == 20 then -- change number to stage
    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId2) -- make Id2 the id of the diff cost
else
if game.Players.LocalPlayer.leaderstats.Stage.Value == 30 then -- change number to stage
    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId2) -- make Id2 the id of the diff cost
else
if game.Players.LocalPlayer.leaderstats.Stage.Value == 40 then -- change number to stage
    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId2) -- make Id2 the id of the diff cost
else
if game.Players.LocalPlayer.leaderstats.Stage.Value == 50 then -- change the number to the stage
    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId2)

    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId3)

    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId3)
else
if game.Players.LocalPlayer.leaderstats.Stage.Value == 90 then -- change the number to the stage
    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId3)
else
if game.Players.LocalPlayer.leaderstats.Stage.Value == 100 then -- change the number to the stage
    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId3)
else
if game.Players.LocalPlayer.leaderstats.Stage.Value == 110 then -- change the number to the stage
    game:GetService("MarketplaceService"):PromptProductPurchase(player, productId3)

end
end
end
end
end
end
end
end
end
end
end
end
end

First of all, indent your code, second of all, use elseif instead of else and then if like this:

elseif game.Players.LocalPlayer.leaderstats.Stage.Value == 110 then

and third of all, you didn't put the bracket to close the mousebutton1click, change the last end at line 68 to:
