I assign g as the key but when i press other buttons the code still run help?

it might be a stupid error but every time i press a key my camera changes the problem is that i assigned g as the key and for some reason any button i press it runs the code and i'm not sure why here is the code.

buttonPressed = false
mouse = game.Players.LocalPlayer:GetMouse()

mouse.KeyDown:connect(function(key)
	buttonPressed = true 
	if key == "g" then
		end
end)
	
	mouse.KeyUp:connect(function(key)
	buttonPressed = false
	if key == "g" then
	end
	while wait() do
	if buttonPressed then
		local target = workspace.Part
		local camera = workspace.CurrentCamera
		camera.CameraType = Enum.CameraType.Scriptable
		camera.CameraSubject = target
		
		camera.CoordinateFrame = CFrame.new(target.Position)
		*CFrame.new(2.9,4.6,-22)
		*CFrame.Angles(0,-3.1,0)
	else
		game.Workspace.CurrentCamera.CameraSubject = 	game.Players.LocalPlayer.Character.Humanoid
        game.Workspace.CurrentCamera.CameraType = "Custom"
end
	end
	end)
	

I see your problem. At lines 12-13, you have the function and then you immediately end it with an end. You should move that end to around line 28.
