Hi Gerry, Don't have the variables handy since my old m/c went west, but I thought you needed something like - A:[Variable],[Units] So I'm guessing there should be a comma betwixt AIRSPEED and MACH?

For the jet, it has the disadvantage of not showing mach numbers. So, I'm cobbling together a small supplementary gauge, intending to didplay theM number that's been dialed into the Autopilot with, below it, the current mach number achieved. The text is in but I've not managed either of the two vlaues. Any advice appreciated. At present the gauge xml file reads: <?xml version="1.0"?> <Gauge Name="GW_MACH" Version="1.0"> <Image Name="GW_WIND.bmp"/> <Element> <Position X="45" Y="15"/> <Text X="260" Y="40" Length="40" Font="quartz" Color="#FF0000" VerticalAdjust="Center"> <String>%SELECTED MACH SPEED %</String> </Text> </Element> <Element> <Position X="260" Y="15"/> <Text X="260" Y="40" Length="40" Font="quartz" Color="#FFFF00" VerticalAdjust="Center"> <String>%((A:AP_MACH_VAR_SET, percent))%!03d! </String> </Text> </Element> <Element> <Position X="45" Y="40"/> <Text X="260" Y="40" Length="40" Font="quartz" Color="#00FF00" VerticalAdjust="Center"> <String>%CURRENT MACH SPEED %</String> </Text> </Element> <Element> <Position X="260" Y="40"/> <Text X="260" Y="40" Length="40" Font="quartz" Color="#FFFF00" VerticalAdjust="Center"> <String>%((A:AIRSPEED MACH))%!03d! </String> </Text> </Element> </Gauge> The gauge appears OK but neither of the desired values appear, just a pair of 000 displays.
