I'm sure this is something easy. I had an existing SATB piece with 4 separate staves. I added a fifth staff for S2, moved it below the first staff, went to the first staff, and tried to layer it, but "Layer with next staff" is greyed out. Why would that be?

I knew it was easy. Thanks. I can't believe I got a reply so quickly.
