I need help fixing my script that gives players matter?

I made a script so that when a player touches a building, will give that player matter and destroy the building. The only problem is that it doesn’t give any matter. I don’t have any output errors, what is happening? Here’s my script:

game.Players.PlayerAdded:Connect(function(player)
    local debris = player:WaitForChild("leaderstats").Debris
    while true do
        wait(1)

        repeat wait (1) until game.Workspace:FindFirstChild("ClonedMap")

        local ClonedMap = game.Workspace:WaitForChild("ClonedMap")
        local Large_Buildings = ClonedMap:WaitForChild("Large_Buildings")
        local Small_Buildings = ClonedMap:WaitForChild("Small_Buildings")

        wait(2)

        for i,v in pairs(Large_Buildings:GetChildren()) do
            for a,k in pairs(v:GetChildren()) do
                if k:IsA("Part") or k:IsA("BasePart") then
                    k.Touched:Connect(function(hit)
                        if hit.Parent:FindFirstChild("Humanoid") then
                            v:Destroy()
                            player.leaderstats.Matter.Value = player.leaderstats.Matter.Value + 10
                            print(player.Name.." destroyed a large building!")

                        end
                    end)
                end
            end
        end




        for i,v in pairs(Small_Buildings:GetChildren()) do
            for a,k in pairs(v:GetChildren()) do
                if k:IsA("Part") or k:IsA("BasePart") then
                    k.Touched:Connect(function(hit)
                        if hit.Parent:FindFirstChild("Humanoid") then
                            v:Destroy()
                            player.leaderstats.Matter.Value = player.leaderstats.Matter.Value + 10
                            print(player.Name.." destroyed a small building!")

                        end
                    end)
                end
            end
        end
    end
end)
