Hi Jeremy,
I’ve been working directly in the experiment farm, and I synced with the github URL given in the guide once again, and it didn’t work. However, since I didn’t see the file PennElement_eyetracker.js in my experiment, I uploaded it directly into the controllers section, and it worked! It threw an error saying that eyetracker was defined more than once, but the demo experiment seems to have worked as it should’ve. I guess I should just upload that file directly to our experiment. Thanks!
