Help with (complex?) ties

[Trevor Fancher]

Hi Lilyponders!

I am trying to get http://fancher.org/want.png but as far as I can get 
is http://fancher.org/want.png .  Those red and green lines are the 
desired ties.  If someone could give me a few pointers as to how to add 
those ties in, I would be really appreciative.  The code I am using can 
be found at http://rafb.net/p/DhdIdu66.html .


Thanks for your time,

Trevor Fancher
