ChildAdded() Event not Firing?

c.Lanes.LeftLane.ChildAdded:connect(function(R)
l=n.Name
s=Notes.Name
R.Name=tostring((l)..(s))
print(R)
Lane.Value=R:GetFullName()
end)

Variables

c=script.Parent.Game.Board -- GUI Object
n=(c.Note) -- NumberValue bool
Notes=c.Notes --NumberValue bool
Lane=c.Lane -- Gui Frame

I don't know why but for some reason the event doesn't fire when a child is added to

c.Lanes.LeftLane I get 0 errors when testing the scripting in Solo Mode.

I think that you're meaning .Value, rather than .Name on lines 2 and 3

Tell me if i'm wrong.

c = script.Parent.Game.Board
n = (c.Note)
Notes = c.Notes
Lane = c.Lane

c.Lanes.LeftLane.ChildAdded:connect(function(R)
	l = n.Value
	s = Notes.Value
	R.Name=tostring((l)..(s))
	print(R)
	Lane.Value = R:GetFullName()
end)

It doesn't work because you tell it to print R, and not R's name. Here's the fixed script:

c.Lanes.LeftLane.ChildAdded:connect(function(R)
	l=n.Name
	s=Notes.Name
	R.Name=tostring((l)..(s))
	print(R.Name) --If it's just "R", then it tries to print userdata, and not a string (R's name)
	Lane.Value=R:GetFullName()
end)
