local Result = MouseCast:RayCast()

				print("d")
				
				Selected = Result.Instance.Parent
				CreateNewBoxUi(Selected)

function RayCast:RayCast()

	local MousePos = UIS:GetMouseLocation() - GuiService:GetGuiInset()
	local UnitRay = RayCast.UnitRay()
	local Origin = UnitRay.Origin
	local Direction = UnitRay.Direction
	local RayResult = workspace:Raycast(Origin, Direction * SettingsModule.MaxRayDistance, RayCast.Params())

	return RayResult

end

It skips the first if statement and moves to the other statement.
When I click on a character, it doesnt do anything.

Change if Selected == nil then to if Selected ~= nil then.
