You added a new hit test. Use your prints on code you already have.
script.Parent.Touched:Connect(function(Hit)
if Hit and Hit.Name == "stop1" then
script.Parent.STOP1.Enabled = true
script.Enabled = false
end
end)
This script will hit stop many times with no debounce.
Start off by printing hit just to see what’s going on
if Hit and Hit.Name == “stop1” then – no need to test hit twice here also.
