Save just the element at the top and then get the element value inside the click handler function.

To expand on lasjorg’s answer:
You are saving the value of the input element as soon as the script loads. As such, it will always be empty. Instead you need to reference the input element at the beginning, and only check it’s value in the event listener, to make sure that it’s always getting the current value when you press the button.
