<script>
  var inputElement = document.getElementById("my_input");

  inputElement.addEventListener("input", function() {
    this.value = this.value.toUpperCase();
  });
</script>

Hello. Thank you so much for your response. I tried your method and method’s similar to it and they continue to not work. I’m assuming the issue is something very simple that I’m failing to recognize? Do you see any errors in the screen caps below?

Thank you!
