I am trying to associate a sound with an XML gauge using Bill Morad's XML Sound Gauge on a simple 2-position switch (ND switch in the 747 Cab file). Have added the line as fillows:(L:Nav Display Switch, bool)(L:Nav Display Switch, bool) ! (>L:Nav Display Switch, bool)The click sound is there but the switch gauge has become inoperative. What have I done wrong, or where can I go to get more detail tutorials on this?

You can't use more then one <Click> or more then on <Click Event... line or both of them in one mouse area. Try a combined <Click> line instead e.g.:<Click> (L:Nav Display Switch, bool) ! (>L:Nav Display Switch, bool) 1 (>K:TOGGLE_AFTERBURNER1) </Click>Arne Bartels

> > > (L:Nav Display Switch, bool) ! (>L:Nav Display >Switch, bool) > > > Wow! Finally, I can help somebody else for a change... :)Try this instead: (>K:Nav Display Switch) >K:TOGGLE_AFTERBURNER1)Replace the > with "& g t " of course if you are not using an XML editor.No, there really isn't a great amount of information available (yet) besides Arne's collection of information.Once I get done with my Socata TB20GT panel project, I hope to start collating information and putting it all on one site... but that will be awhile yet... :(
