P3D v1 Engine Feathering - Reentry into coding

[TooLowGear]

Hey All. I haven't been coding for a few years, real life flying and jobs. I have a situation: A sim which does not have a keyboard, or mapped key commands for a keyboard, and can not use FSUIPC must be able to feather the prop on a multi-engine recip. There are no buttons available to press physically so anything done has to be software driven. The sim uses a throttle quadrant but no buttons are on it. This sounds like a riddle but this is what I have to work with.

My idea was to use a gauge to test for feathering conditions of:
Prop Handle 30% or less and prop feather = 0, the reverse also has to occur to unfeather the prop. Here is my attempt. I am pretty sure I am mis-using the K variable here. Any help is greatly appreciated!

<Gauge Name="TESTFEATHER" Version="0.1">
<Size X="00" Y="00"/>
<Gauge>
<Element>
  <Select>
    <Value>
		(A:PROPELLER_1_FEATHERED,bool) 0 ==
		(A:RECIP_ENGINE1_PROP_LEVER_POS,enum) 0.3 &lt; &amp;&amp;
			if{
				1(&gt;K:KEY_TOGGLE_FEATHER_SWITCH_1)
			}

		(A:PROPELLER_2_FEATHERED,bool) 0 ==
		(A:RECIP_ENGINE2_PROP_LEVER_POS,enum) 0.3 &lt; &amp;&amp;
			if{
				1(&gt;K:KEY_TOGGLE_FEATHER_SWITCH_2)
			}

		(A:PROPELLER_1_FEATHERED,bool) 1 ==
		(A:RECIP_ENGINE1_PROP_LEVER_POS,enum) 0.3 &gt; &amp;&amp;
			if{
				0(&gt;K:KEY_TOGGLE_FEATHER_SWITCH_1)
			}
		(A:PROPELLER_2_FEATHERED,bool) 1 ==
		(A:RECIP_ENGINE2_PROP_LEVER_POS,enum) 0.3 &gt; &amp;&amp;
			if{
				0(&gt;K:KEY_TOGGLE_FEATHER_SWITCH_2)
			}
    </Value>
  </Select>
</Element>
</Gauge>

And Bill, if you see this: Thanks for all the help in the past, those conversations on the forum were really helpful.

FSX? Try these and see if you get the expected results:

(A:PROP FEATHERED:1, bool)	

(A:GENERAL ENG PROPELLER LEVER POSITION:1, percent)

1 (>K:TOGGLE_FEATHER_SWITCH_1)

(A:PROP FEATHERED:2, bool)	

(A:GENERAL ENG PROPELLER LEVER POSITION:2, percent)

1 (>K:TOGGLE_FEATHER_SWITCH_2)

One other point, TOGGLE state may not settable by 1 or 0 ... that is, it's just a toggle and you probably don't need to assign it a value. (>K:TOGGLE_FEATHER_SWITCH_2) and it's "on", (>K:TOGGLE_FEATHER_SWITCH_2) again and its "off".

Help this helps

Thanks!

The sim is P3D.
