There are improperly-nested parens on the second-to-last line.

Those kind of errors can be detected quickly after practicing a lot and it's very important. If your'e getting troubles detecting those errors you can try using a program as help. I tend to use checkmarx these days and it does a good job.
Anyway, good luck with that.

@benhart,
if the tool you advertise is so great why don't you show use how it could solve this particular problem?
I suspect that you just want to advertise but are not really interested to help the OP to solve his problem.
