**UPDATED** Why wont this script add values to leaderstats? [closed]

What the title says. Also how do I make it instead of when the player is added, its when the player clicks on the monitor. Surface GUI with clickdetector script is already done

What I am trying to do is make it when a person clicks on the startermonitorupgraded, it activates the surfaceGUI(it does) but it dosent add the values that I have set in the script.

game.Players.PlayerAdded:Connect(function(plr)
    if game.Workspace.StarterItemsUpgraded.StarterMonitorUpgraded.SurfaceGui.Active == true then  
        wait(math.random(1, 2))
        print("Hi")
        game.Players.LocalPlayer:WaitForChild("leaderstats"):WaitForChild("Followers").Value = game.Players.LocalPlayer:WaitForChild("leaderstats", 120):WaitForChild("Followers").Value +1
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >130 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(1,2) 
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >250 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(1,3)
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >350 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(1,4) 
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >410 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(2,4)
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >500 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(2,5) 
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >600 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(2,6) 
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >700 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(2,7) 
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >775 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(3,7) 
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >845 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(3,8) 
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >950 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(3,9) 
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >1150 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(3,10)
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >1450 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(3,11)
    elseif game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value >1750 then game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value = game.Players.LocalPlayer:WaitForChild("leaderstats").Followers.Value + math.random(3,12)

    elseif game.Workspace.StarterItemsUpgraded.StarterMonitorUpgraded.SurfaceGui.Active == false then 
        return nil
