Substitution

[Palmer, Ralph]

Greetings -

I'm running LilyPond 2.11.27 (although the files, after running
convert-ly, say 2.11.23) under Windows XP2000, SP2.

Great program! I just wish I knew everything about it. I'm gaining on
it, though.

In the following code, why doesn't my substition work?

Thank you for your help and for your contribution to the program,

Ralph
