!Problem solved! COMPOUND BUTTON CONDITIONS

[Pmax]

Hi, I want to try and program a button on my VBK Gladiator NXT EVO joystick for use in MSFS 2020, e.g. C172 G1000. My plan is that I should activate a function (Pressing the FLP button in the G1000 MFD.) The function should be that when I press the button on the joystick, the function should be activated, but only when another button is NOT active.

According to the instructions "FSUIPC7 for Advanced Users" it should look like this: "n=CP(–j2,b2)j,b," But in my inifile the button press looks like this:
28=PC,28,CIAS1000_MFD_1_Range_Cursor,0.000000 -{Input Event}-. Here "28"= the button on the joystick, and no Joy number is displayed. But in this case it does:
18=PC,193,CIAS1000_MFD_1_VS_DN,0.000000 -{Input Event}-
Joy=1, Button=93.
But how can I program (28=PC,28,) to only work when (18=PC,193) is not pressed?
I have tried this:
29=CP,(-193),28,CIAS1000_MFD_1_VS_DN,0.000000 -{Input Event}- but it does not work!
What am I doing wrong?- Can you show me how to do it? Should "29=" be "n=" instead?
Many thanks in advance.
Kind regards
Per

FSUIPC7.ini

I solved it with the help of this forum. I just had to dig a little deeper.
I saw in my button assignments window what my buttons actually were.
I hadn't referenced the correct Joy, and button tag.
So now the string looked like this, and it works.

29=CP(-C,193)C,28,CIAS1000_MFD_1_VS_DN,0.000000 -{Input Event}-
