You should get an text editor that shows you matching parens by indenting the lines according to nesting level.  This would have shown you your error quickly.

Missing that, you got an error message involving FORGD.    It is not uncommon that it takes a line or two for the compiler to understand there is something wrong, so look above the FORGD line.  

And what do we find on the line above?  An extra right parenthesis.  There is also a missing right parenthesis a few lines down, which is why you don't get an error about unbalanced parentheses.

Again, get a Lisp-aware editor to avoid these kind of problems.
