Welcome to the forum @mnkenchor4206

  1. Here is the console error:

Uncaught TypeError: Failed to execute ‘addEventListener’ on ‘EventTarget’: 2 arguments required, but only 1 present.

  1. What have to done to debug?

  2. Here is a pointer on how to structure the addEventListener method.

  3. The onlyA function may not be the correct approach.
    What if any other single letter is submitted?

  4. In the html file you need to close the html opening tag.

  1. Consider nesting appropriate text in the button element.
  1. It may help to write down in your own words what the checker is supposed to do. That way you have a starting point to formulate the logic required.

The first project is usually the toughest. But you will learn so much.

Happy coding
