I'm connecting to Mavenlink to pull time cards  and running the below code in the Developer Console.  2/3s down the page my last if-statement block of code causes the code to fail without any explanation.  Commenting out that if-statement block causes a successful execution.

I hope someone can help..I hope it's a silly little thing I missed and I can stop banging my head in the wall....
