script stops working after upgrade

I noticed that my dropdown select list has stopped working since wordpress was automatically upgraded to 3.9.7 from 3.9.6.

Script is a simple drop list that can be selected and user can be taken to a product page. The script works elsewhere so the script does not seem to be the problem. Unfortunately I do not have a full backup from before the upgrade.

If there is a better suggestion besides this script I would do that instead.

‘<script>// <![CDATA[
function land(ref, target) { lowtarget=target.toLowerCase(); if (lowtarget==”_self”) {window.location=loc;} else {if (lowtarget==”_top”) {top.location=loc;} else {if (lowtarget==”_blank”) {window.open(loc);} else {if (lowtarget==”_parent”) {parent.location=loc;} else {parent.frames[target].location=loc;}; }}} } function jump(menu) { ref=menu.choice.options[menu.choice.selectedIndex].value; splitc=ref.lastIndexOf(“*”); target=””; if (splitc!=-1) {loc=ref.substring(0,splitc); target=ref.substring(splitc+1,1000);} else {loc=ref; target=”_self”;}; if (ref != “”) {land(loc,target);} }
// ]]></script>’

Your help is appreciated.
