I have the following gauge. It uses two bitmaps - however when clicked, it does what it is programmed to do, but does not display the second bitmap. Can anyone see what I'm missing?(A:Fire Engine1 handle, enum)0 (>K:TOGGLE_FUEL_VALVE_ENG1) 1Thanks for any help. Andrew

Andrew,, G'Morn to ya.. 2 things.. 1 major & 1 very minor..#1 (A:Fire Engine1 handle, enum) (A:Fire Engine 1 handle,enum) is not a valid A: type variable. For valid A: variables (XML only) see the parameters.doc in the panels SDK or a_vars.txt in XMLgau01.zip... (A:General eng1 fuel valve, bool) should work. When using an A: type variable, some type of describing unit must be provided. For those see units.doc in the panel SDK. #2 very minor... 0 (>K:TOGGLE_FUEL_VALVE_ENG1) 1 Even though this works no describing numbers need to be used. I.E. the 1 and zero. The K: type writing variable already knows it's either on or off because of the "TOGGLE" ... No biggy whatsoever. For valid K: type vriables see EventIDs.doc in the SDK or k_events.txt from XMLgau01.zip.. This should get you going...P.S. BTW the screeny you sent looks GREAT!!! you must be very close to done ???

Thanks for the tips again Roman, working now :-)I had forgotten about the a_vars.txt! I'll have to dig that up. Thanks for the comments - the main panel is complete. The overhead now has working light systems, hydraulic select system, anti-ice systems and now working fire handles :) I still have work to do on the pedestal and FE panel. I need to get hold of some bitmaps for these panels. I know a guy who flies her, so maybe he could get me a few shots if I pass a digital camera and err...a bottle of whiskey his way! :-lolThanks again.Regards,AndrewMain panel:http://ftp.avsim.com/dcforum/User_files/3d8861e730eb3a27.jpgOverhead:http://ftp.avsim.com/dcforum/User_files/3d886225316dd1ab.jpg
