I have installed it into panels, however trying to add it to the PMDG 77w.

[fltsim]
alias=PMDG 777-200LR\panel
window1=GroundhandlingV6

[Window1]
size_mm=204,65
visible=0
window_size= 0.20,0.09
window_pos= 0.0,0.05
background_color=16,16,16
type=SPECIAL
gauge00=RCB_Groundhandling6!PushbackDisplay, 2,2,74,61
//gauge01=RCB_Groundhandling6!PushbackStatesStandard, 0,0                       //Using embedded FSX/P3D Pushback feature
gauge01=RCB_Groundhandling6!PushbackStatesFreeControl, 0,0                    //Using Pushback alternative
gauge02=RCB_Groundhandling6!Taxispeed, 79,2,64,61
//gauge03=RCB_Groundhandling6/AVM32!Maryadi_lv2av, 0, 0                         //For FSX and P3Dv2,3
gauge03=RCB_Groundhandling6/AVM64!Maryadi_lv2av, 0, 0                         //For P3Dv4 
gauge04=RCB_Groundhandling6!Brakes, 146,2,56,61
//gauge05=RCB_Groundhandling6/XMLSound32!Sound, 0,0,0,0, ./Gauges/RCB_Groundhandling6/XMLSound.ini  //For FSX and P3Dv2,3            
gauge05=RCB_Groundhandling6/XMLSound64!Sound, 0,0,0,0, ./Gauges/RCB_Groundhandling6/XMLSound.ini   //For P3Dv4             
gauge06=RCB_Groundhandling6!NoseWheelRadius, 0,0                         //Establishes the NoseWheelRadius of the aircraft

Nothing happens - how can I get it working?

Thanks

PMDG 777-300ER\panel    <--------  You inserted the config into the wrong panel. You need to install into the main PMDG 777-200LR/Panel folder.

Then add the window below.

[Window22]
size_mm=204,65
visible=0
window_size= 0.20,0.09
window_pos= 0.0,0.05
background_color=16,16,16
type=SPECIAL
gauge00=RCB_Groundhandling6!PushbackDisplay, 2,2,74,61
//gauge01=RCB_Groundhandling6!PushbackStatesStandard, 0,0                       //Using embedded FSX/P3D Pushback feature
gauge01=RCB_Groundhandling6!PushbackStatesFreeControl, 0,0                    //Using Pushback alternative
gauge02=RCB_Groundhandling6!Taxispeed, 79,2,64,61
//gauge03=RCB_Groundhandling6/AVM32!Maryadi_lv2av, 0, 0                         //For FSX and P3Dv2,3
gauge03=RCB_Groundhandling6/AVM64!Maryadi_lv2av, 0, 0                         //For P3Dv4 
gauge04=RCB_Groundhandling6!Brakes, 146,2,56,61
//gauge05=RCB_Groundhandling6/XMLSound32!Sound, 0,0,0,0, ./Gauges/RCB_Groundhandling6/XMLSound.ini  //For FSX and P3Dv2,3            
gauge05=RCB_Groundhandling6/XMLSound64!Sound1, 0,0,0,0, ./Gauges/RCB_Groundhandling6/XMLSound.ini   //For P3Dv4             
gauge06=RCB_Groundhandling6!NoseWheelRadius, 0,0                         //Establishes the NoseWheelRadius of the aircraft

 

The problem was...... You inserted the Groundhandling6 panel config into the wrong folder.  (PMDG 777-300ER\panel ) feeds from the main PMDG 777-200LR\panel folder. 

 

Thanks, working!
