DrDave- Posted November 13, 2023 Report Share Posted November 13, 2023 I have been struggling with this error for the past 2 hours. Can't seem to clear it. I have reread the Lua documents and viewed several FSUIPC7 Plugins. The error and code are: ********* LUA: "Alpha_Buttons" Log [from FSUIPC version 7.3.25] ********* 3128781 System time = 13/11/2023 11:33:10, Simulator time = 11:33:15 (16:33Z) 3128781 LUA: beginning "C:\FSUIPC7\Alpha_Buttons.lua" 3128781 *** LUA Error: C:\FSUIPC7\Alpha_Buttons.lua:13: 'then' expected near '=' 3128797 >>> Thread forced exit (ipc.exit or os.exit) <<< 3128797 System time = 13/11/2023 11:33:10, Simulator time = 11:33:15 (16:33Z) ********* LUA execution terminated: Log Closed ********* 7 k1 = 13 8 k2 = 14 9 function TOGGLE_AVIONICS_MASTER(joynum, button, downup) 10 b = button 11 avstate = ipc.readSD(0x2E80) 12 display.show(h, 1, "Avionics " .. avstate ..

A single '=' is used for assignment, not conditionals. Link to comment Share on other sites More sharing options...

"On Off") The display library is for WideClient only. If not using WideClient. you probably want to use ipc.display. However, the SimConnect text display functions are no longer working in MSFS. You may see something, but it is not reliable and the underlying functions have been deprecated. For displaying information in a window from lua, you should use the Wnd library.
