Export by Label

I’m using Audacity 2.0.3 and I am a total beginner. I successfully recorded one LP through the USB connection. I used Export Multiple and under “Split files based on” I was able to select “Labels” rather than “tracks”. This time around the “Label” button is greyed out and I cannot select it. Does anyone know how to remedy this problem?

Looking at the obvious first, does your project have labels?

There’s a tutorial here that may help: http://manual.audacityteam.org/o/man/splitting_a_recording_into_separate_tracks.html
