Do you have the correct file path in the script tag? If it's in another folder, you have it pointed correctly to that folder?

Hello Daniel,

There is a Simple Step To Resolved Why jQuery ( $ ) is not defined.

Step one :

Check That jQuery Script Source is Found and Working Properly

Step Two :

Try Testing Code , Is it work for long hand jQuery instead of short hand dollar sign :

jQuery(document).ready(function(){
 alert("jQuery is working properly");
});

If the above code is working, It usually due to the fact, That some other libaries such as Libaries in Wordpress are take over the short hand dollar sign which make the jQuery code doesn't run properly.

However , If the above code isn't working, 

     <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>

Try Include Script.

It may be the fact that the download jQuery is broken.

Thank you.
