This script I have on my site is causing some unexpected error: Uncaught ReferenceError: $ is not defined
it should rewrite function of enter to act as a tab within the inputs on site form instead of submitting that form.

<script type=text/javascript>

 $('input').keypress(function(e) {

  if (e.which == 13) {

    <--! says error is here within the $ symbol -->

    $(this).next('input').focus();

    e.preventDefault();

  }

 });

</script>

Thats probably because jQuery isn't defined. (I'm assuming you are using juery).

Try including jQuery first:

<script src=https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js></script>

<script type=text/javascript>

 $('input').keypress(function(e) {

  if (e.which == 13) {

    <--! says error is here within the $ symbol -->

    $(this).next('input').focus();

    e.preventDefault();

  }

 });

</script>
