I want to replace the "No students enrolled" with the output from displayStudents(testArray) when it runs. I have attached the .js and .html files for reference.
Thanks!

Seems to work for me. But the subject line of your forum topic is truncated, what is it meant to say?

Could it be due to

CODE
studentEnrolSummaryRef.innerHTML = displayStudents(studentList);

that uses the empty studentList array?

Nope, I have been testing a simplified version that doesn't work either

The answer is "debugging". Instead of staring endlessly at stuff trying to see the problem (which doesn't work), you put in debugging stuff. If the script file doesn't seem to be running, put "alert('fish');" near the beginning. You will immediately know when and whether it is being called.

That doesn't explain the javascript errors though, a broken path to the JS file would prevent the script from running at all. I wouldn't worry about Scrimba though, use your web browsers' developer tools instead (both Firefox and Chromium-based).

And like Brian said, methodical debugging is the key...
