IE10 CDATA

IE10 does not see function definitions that earlier versions see.

when the input field is clicked (see below) the function SubmitCross is not seen as defined

<script>
<![CDATA[
function SubmitCross()
{
var axis1 = "select_flavor" + document.all.item('axisflavor1').selectedIndex + "_axis1";
var axis2 = "select_flavor" + document.all.item('axisflavor2').selectedIndex + "_axis2";
var variable1 = document.all.item(axis1).value.split(".");

if (variable1[0].indexOf("error") == -1)
{
var questionY= variable1[0].split("-");
var implicitTypeY
= variable1[1].split("-");
