Okay....
Also don't leave columns without any data in them for Take-Off and Landing, they must have flaps assigned to them or delete them.
OK, that was the clue I needed. I must have created this perf file by using an existing one as a template, and I ended up with extra flap setting columns. I deleted that file and created a new one from scratch and it works fine. Yeah! Thanks for all the help. I'm having a bit of trouble setting up the hot keys but I'll work on it some more before bothering you again.
