Thanks Rudel, I'll check it out.
I think I found my problem...I'll have to test again.
As per the above thread, I didn't add a flag and "time is more", so as soon as the conditions triggers, the flag is 'false' thus the message doesn't fire...that's my current though anyway.
Out of test time for tonight.
A bit confused about "cockpit param equal to" vs "cockpit param equal to another" as I've seen advise instructing both.
I'll check that mission out as well, thank you.
