Hi Vlad ! Thanks for the reply and answer. Even though I've been playing around with your software for a couple of months now, I've never run into an scenario like this, so I pretty much don't know where to start. I looked for parameters that were already created with those names (Battery2_Switch and Ann_Test) but couldn't find them. Also looked in the X-plane folder for some file that could give me a hint on what are you talking about, but nothing. So I'll please appreciate if you can point me at least where to look or start at. Or if there is a tutorial within the website that can help me out, please link it for me. Thanks !
