Writing a negative value to a LVAR

[MarkStallen]

I've in my FSUIPC.ini :

6=A32NX_ECAM_SD_CURRENT_PAGE_INDEX=UB66C8

and in my LUA :

LastECAM = ipc.readSB("66C8")
LastECAM = LastECAM + 1
if LastECAM == 12 then    
    LastECAM = -1
end
ipc.writeSB("66C8",LastECAM)

Everything works and the LVAR is set in MSFS 2020 except for the moment I write -1 to the variable, then the variable doesn't change.

 

If I look in the aircraft behaviour in MSFS , it's possible to set the variable to -1

It should be...

You are holding it as an unsigned byte (UB) - try changing that to SB.

If it still doesn't work, let me know and I will check using negative values here.
