A line of code needs to be called upon to be executed, in this case, you need to create a function, then call the function to run it. Example:

// this is the function
function theAlert() {
      alert("Warning!");  // this is the message
    }
    theAlert(); // and here is the function call

Hope this helps, cheers.

:warning: Creating and calling a function is not part of this challenge.

Your alert call is correct, but you have some other issues:

  • the code has an extra set of script tags with a src attribute that are not part of this challenge
  • both script tags with the code in between should be inside the body element

There's no need to create an extra function for this challenge.
