player.CharacterAdded:Connect(function(character)

    script.Parent = character:WaitForChild("ShieldPoints")
    wait(4)
print(script.Parent.Name)


script.Parent.Changed:Connect(function()     
    if script.Parent.Value < script.Parent.MaxShieldPoints.Value then


        repeat
            wait(1)
            print("Regenerating Stamina")
             script.Parent.Value = script.Parent.Value + script.Parent.MaxShieldPoints.Value/10
            until script.Parent.Value == script.Parent.MaxShieldPoints.Value
