I am attempting to take the last 5 digits from a 15 digit number that the user of the form will enter in and use those last 5 to fill a hidden field to be used for the template and our records tracking. 

I have tried some versions of codes that have been posted here already and have not had any luck. This is what it looks like right now.

I need the last 5 digits from field52 to enter into field 53. and I am quite stuck.

 

Thanks in advance.

See this thread for an example of how to achieve this.

$(document).ready(function () {   
  $('#Field52').on('change', function() {
    $('#Field53').val($(this).val().substr($(this).val().length - 5));
  });
});
