Ian,
Thank you for the info. I will give it a go. See if I can manage my way around. If I'll get stuck there is google and other tools out there to help at the end of the day I can seek for help here as well.
HMA,
Thank you too. I've tried your settings but not all of them work. But never mind it gives me an idea. I have noticed though that your lua script is modified in a different way from what I've read earlier. I guess there are various ways of achieving the same results. May I ask you ... how did you know all the values for down = 3001, up = 3001, cockpit_device_id = 7, value_down = 0.2, value_up = 0.1? Is there some sort of reference you use?
Kind regards,
Janis
