Yes, they were commas --I'm an idiot. It is so easy to enter the tab lyrics that I was going too fast and not watching what I was doing. I entered a bunch of commas for one note.
I have the lyrics entered and the song saved in a new file. I will try playing it and hope for the best.

I have never used Real Band. I have a RB icon but when I opened it said it hadn't been registered and asked for a number. I will have to dig up the BiaB number and see if it works. I don't even know what RB is.
