Alieldien First of all the in the input section of the HTML, you have not included type text into " " . You can do it like type="text". Second mistake you can't get a variable from a function to another function. It will cause an error. Third, you have not got the value of input in the inp variable. You can do it like this. var inp = document.getElementById('input').value;
