Harm:

Wow!

You are amazing!  Thank you so much.  The second possibility is going 
to work very well.  Also, thank you for the comments as well.  I really like 
LIlypond but as I am the only person in my area, that I know of, that 
uses Lilypond I am only able to learn from the manual, docs, 
references, self-instruction, and fine people like yourself. 

Thank you!
