Hello I made a simple gauge so I can hear Apu sound, but I want to hear that sound outside the aircraft only, in the spot view. What formula has to be written? Can someone please help me.. <Gauge Name="Apu" Version="1.0"> <Element> <Select> <Value>(L:Apu, bool) </Value> <Case Value="0"> <Image Name="Dummy.bmp" /> </Case> <Case Value="1"> <Image Name="Dummy.bmp" /> </Case> </Select> </Element> <Mouse> <Click> (L:Apu, bool) ! (>L:Apu, bool) == if{ 2 (>L:Dsd_xml_Apu,enum) </Click> <Cursor Type="Hand" /> </Mouse> </Gauge>

You will probably have better luck posting your question in the Aircraft and Panel design forum. :(
