Xml compilation problem

Question

Please can somebody help. I have copied the example out of
the programming action script 3 .pdf (page 324) and I cant get it
to compile. The error is 'Access of undefined property myXML.'. I
have listed the code below. Can someone help
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:Script>
<![CDATA[
var myXML:XML =
<order>
<item id='1' quantity='2'>
<menuName>burger</menuName>
<price>3.95</price>
</item>
</order>;
trace(myXML.item[0].menuName);
]]>
</mx:Script>
</mx:Application>

Answer 1

It looks like the solution to this one is to put the word
“static” in front of the variable declaration:
static var myXML:XML =
<order>
<item id='1' quantity='2'>
<menuName>burger</menuName>
<price>3.95</price>
</item>
</order>;
It seems that when you put function calls directly into a
<mx:Script> tag – that is, calls that are not enclosed
in function definitions of their own -- then those are treated as
static calls, and they can only operate on static variables.
