Can you please see to the travis issues ?
Also, please write a system test to ensure the correctness of your code. Thanks

As we may soon be making big changes to the dashboard, i think we can skip system tests in this instance. Thank you very much!!!

Thank you!!! Can you give it one more try at stable.publiclab.org once it rebuilds? Awesome!
