This is my XML code, it displays fine in FSPS and I don't see anything wrong with it, but whenever I run FSX the gauge doesn't show

<?xml version="1.0" encoding="utf-8"?><Gauge Name="ADI_annunciator" Version="1.0"><Image Name="adi.bmp"/><Element>	<Position X="137" Y="168"/>	<Select>	   <Expression>	      <Minimum>0.000</Minimum>	      <Maximum>1.000</Maximum>	      <script>(A: Autopilot Vertical Hold, bool)<script>	   </Expression>	   <Case>	      <ExpressionResult>0.000</ExpressionResult>	      <Image Name="alt_vrt_off.bmp"/> 	   </Case>	   <Case>	      <ExpressionResult>1.000</ExpressionResult>	      <Image Name="alt_vrt_on.bmp"/>	   </Case>	</Select></Element><Mouse>   <Tooltip ID="Attitude Indicator"/></Mouse></Gauge>

Can anyone please help me debug this?

Try placing the gauge somewhere else. If you tried to place the gauge say, on top of the ADI, which will surely have a "masked" image, the updating of the ADI will keep the annunciator from showing.Roman
