Hi everybodyHere is the situation.I'm on final on an RNAV approach, minimums set to 510 baro and 500 dialed into the alt select window, VNAV and LNAV are on. I don't see the runway lights at minimums so i hit the TOGA screw. This turns off the autopilot so i put flaps up and gear and start climbing to the missed approach altitude of 3500 feet. I also dial this into the alt select window. I go to engage VNAV and it says "unable crz alt" What am I doing wrong. Would somebody be able to guide me to a tutorial or show me what to do from being on final to going around and coming back for another approach.Many thanks!

Why'd you make another post?

I'm sorry I can't see my old post, could you put the link in please?
