I know there is an error but I don't understand the message to find the error.

[Jay Hamilton, Sound and Silence]

Below is the error message and the file it refers to.
I've changed everything I can think of to get it to 
compile but I don't know why there is a problem either 
with line 36 or with the one expression beginning with #.
