the problem is in your echo statements.  see below.

the ` character starts a shell inline expansion.  change it to '

[ btw, this is an excellent example of a place where debugging
was greatly sped up by using an editor with shell syntax
coloring.  the odd colors in your script were immediately
apparent.  (i use vile.  i assume vim and emacs would be helpful
as well.) ]
