thanks steve

<script> var = 0;  var itemkey = localstorage.key(i); var values = localstorage.getitem(itemkey); values = values.split(";"); var name = values[0]; var company = values[1]; var contactnumber = values[2]; var email = values[3]; var address1 = values[4]; var address2 = values[5]; var suburb = values[6] var postcode = values[7]; var comments = values[8]; var bags = values[9]; var distance = values[10]; var hdelivery_fee = values[11]; var hprice = values[12]; var htotal_notax = values[13]; var hgst = values[14]; var htotal_tax = values[15]; var hordernumber  = values[16];   document.write('name: ' + name + '<br />'); document.write('company: ' + company + '<br />'); document.write('contact: ' + contactnumber + '<br />'); document.write('email; ' + email + '<br />'); document.write('address; ' + address1 + '<br />'); document.write('address; ' + address2 + '<br />'); document.write('suburb; ' + suburb + '<br />'); document.write('postcode; ' + postcode + '<br />'); document.write('comments; ' + comments + '<br />'); document.write('number of bags; ' + bags + '<br />'); document.write('distance; ' + distance + '<br />'); document.write('delivery fee; $' + hdelivery_fee + '<br />'); document.write('price of bags; $' + hprice + '<br />'); document.write('total ex-gst; $' + htotal_notax + '<br />'); document.write('gst; $' + hgst + '<br />'); document.write('total inc gst; $' + htotal_tax + '<br />'); document.write('hordernumber; ' + hordernumber + '<br />');   </script>

to display last value of array should use values[values.length-1].

this guarantee absolute last one.
