Well, take a look at line 40, since that is where the error is occurring.

Im not seeing any error in that line, it is set up the same way as the line above it, which doesn't show an error, and copied in the same manner as in my book..

Well, perhaps you should post that line then, because personally I don't want to spend time counting down 40 lines in all that code that you posted (and it's doubtful that anyone else does either).
And read carefully the description of the error - it's pretty straightforward.
