What would you like or expect to see?

In my experiment, I ask general knowledge questions. Participants are instructed to enter their answer into a free-form input field (HTML page). I want to provide feedback on whether their answer is correct or not. The feedback will be given as images: a smiling emoji for a correct answer, and a sad emoji for an incorrect one.

What is currently happening?

At the moment, the program identifies all answers as incorrect, even though they are actually correct. It seems that the program is not recognizing the correctness of my answers.

Please describe the steps needed to reproduce this phenomenon

Now, I have to fix the problem and get Lab.js to recognize my answers as corect or incorrect. Please find the file attached. I have problems with the feedback_knowledge_test Screen :/

Finally, please tell us which browser you're using (and the version thereof)

I am using microsoft edge or safari.
I would be very grateful if anyone could help me.
