Script Error on 25 + 5 Timer

Hi all- I’m running into a script error message when trying to run the tests for the 25 + 5 timer (see below) and I can’t figure out what it means. Here’s my project- https://codepen.io/hawki2sl/pen/XWqYopb?editors=0111.

Don’t trust the Codepen console. Open the actual browser console. I’d also suggest switching to the development version of the libs to get better error messages.
