Telephone Number Validator (eventListener problem)

JavaScript
1

Hello!

const input = document.getElementById("user-input");
const checkBtn = document.getElementById("check-btn");
const clearBtn = document.getElementById("clear-btn")

checkBtn.addEventListener("click", () => {
  if (input.value === "") {
    alert("Please provide a phone number")  
  }
});

There seems to be no reaction here. Console throws a [TypeError: alertMessage is undefined], same story if i put return before alert.

Any ideas what I’m missing here? Thanks

Are you loading your script.js file in your HTML doc?

Hehehe. Silly me.

It was the default index.js instead of the script.js. Thanks.
