div content disappearing on refresh in IE7

When I refresh the page in IE7 this div content is disappearing:


for(cnc=0; cnc<common_name.length; cnc++)
{
var comname = document.createTextNode(common_name[cnc].childNodes[0].nodeValue);
if(common_name.length>1 && cnc<common_name.length-1)
{
comname.appendData(', ');
divb.appendChild(comname);
}
else{ divb.appendChild(comname); }
}


The html section:

<div id="content">
<script type="text/javascript">
load_catalog("herb");
</script>
<div id="catalog">
</div>
</div>

Apparently IE needed the script to come after the div. Problem solved.
