Why when I click on a part, I get an error?

I got an error in the output saying that "MouseButton1Click is not a valid member of ClickDetector "Workspace.RiotAlarm.ClickDetector" Even if the model has a Click Detector.

Also the Script.

local alarm = game.Workspace.AlarmBO

script.Parent.ClickDetector.MouseButton1Click:Connect(function() alarm.Light.SpotLight.Enabled = true alarm.Light.SpotLight2.Enabled = true end)
