Light control PMDG 777

[muted sparrow]

I am going to use my Overhead Panel with PMDG 777 and try to attribuate light controls For example.
**
PMDG B777 OVHD Flood Light Brightness inc**

(L:OH_PANEL_LIGHT_CONTROL, number) 1 + 100 min (>L:OH_PANEL_LIGHT_CONTROL)

@ 16 - 3.36 / 0 max 5000 min index (>L:switch_25_b) - 9 div s1
:1
**
PMDG B777 OVHD Flood Light Brightness Dec**

(L:OH_PANEL_LIGHT_CONTROL, number) 1 - 0 max (>L:OH_PANEL_LIGHT_CONTROL)

@ 16 - 3.36 / 3000 + 0 max index (>L:switch_25_b)

i found that the switches are 25 A B and 26 27 A B.
But i am not** aware with MF symbol and coding**.

In that case if I use only one it is OK when I placed the potentiometer in the middle but when I use the 2 functions it does not work. independant yes together NO
Perhaps need a function if?
Could you explained to me the right method I used also in HUBHOP the Tools

These light controls works perfectly with encoders but i am interested to understand the coding
If you have a MF documentation.

Many thanks

as an example for a potentiometer with a range of 0 - 1023 the code for the OVHD Flood would be @ 10.23 / 0 max 100 min (>L:OH_PANEL_LIGHT_CONTROL, number) you can read mroe the the RPN sytax which mobflight uses for MSFS here - https://docs.flightsimulator.com/html/Additional_Information/Reverse_Polish_Notation.htm
