im adding a vortex effect to my 737, so you can see that little smoke trail that comes off the flaps when they're down

i've modified an XML gauge from project airbus so i can have it in my plane... it works but there's a catch:

this xml gauge has a max and min speed limit to activate the effect but it doesn't detect if the flaps are up or down

i want the effect to activate only when the flaps are in their 2nd most extented position or lower (the 737 has 8 flap positions, plus fully retracted)

how would i write this condition into the xml file?

this is the code as it is:

- <Gauge Name="WingTipVortices" Version="1.0">
- <Element>
- <Select>
  <Value>(A:AIRSPEED INDICATED,knot) 120 > (A:AIRSPEED INDICATED,knot) 160 < && if{ (>K:SMOKE_ON) } els{ (>K:SMOKE_OFF) }</Value>
  </Select>
  </Element>
  </Gauge>

i realised that, but i couldn't do anything because i don't know the right tag and i don't know how the sintax works, so i can't add a new condition to the whole thing

i want it to check both the airspeed and the flaps to activate.

Thanx for the help
