Compilers are not omniscient, nor were they created by omniscient programmers.
A syntax error in one place will often send the error-reporting routines down a
weird path, and most of the resulting output will be nonsensical. Ken's advice
is good: you have to compile, debug, rewrite, compile, etc. through many
iterations. Usually, on each pass through this loop, the errors and warnings
will be more germane and make more sense. I have certainly seen this with XML
parsers. The language may be well-defined, but some mistakes just don't parse
well enough for the validator to understand what you were trying to write.
When I was attempting to write Fortran in college in the 1960s, submitting it
on punch cards and getting a printout back from the IBM/360 in the computer
center the next day, often the best feedback I got was something like "syntax
error on line 60, runtime 0.2 seconds." I'm glad that those days of learning
programming are over.

Do I really? Oops. Okay. Thanks. I'll go take a look at that. Strangely
enough, JAWS never read that one off, therefore, I must have missed it that
way. And when debugging, I'm surprised that the compiler didn't just tell me
that rather than be obscure about it. Do you think that once I get more into
this, then I'll get used to those obscurities? And ... never mind. I see it
now LOL.

Notice that you have an extra quotation after "userName". ;)
