Code review - PHP syntax error unexpected $end 
Hey guys!  I keep getting a syntax error (unexpected $end), and I've isolated it to this chunk of code.  I can't for the life of me see any closure issues.  It's probably something obvious but I'm going nutty trying to find it.  Would appreciate an additional set of eyes.
