The problem is that the form element you are modifying doesn't exist yet when you rollover it while it's still loading.  This causes an error since it can't find the object.  So you have to set a variable in the onLoad handler for the document.  This will ensure that it is loaded before trying to modify it.

onLoad="loaded=true"

Then in the map areas:
onMouseOver="if (loaded) theForm.out.value='SHOPPING'"

Also be sure to define loaded in the header:
<SCRIPT language="JavaScript">
<!--
var loaded = false;
// -->
</SCRIPT>
</HEAD>

This should fix it for you.
