Help with XML menu

Hello, I am building a nav with XML and I have it working but I am have probs with getting my swf’s to load. Here is the script part of the nav that create’s the action:

// – Execute Action -------------------------------

function executeAction(arg){
// do load movie here: _root.loadMovie(arg)
display = arg;
}

and here is the xml file:

<menu>
<item name=“ABOUT PETRA” arg=“galleryOne.swf”>
<sub name=“WHAT SHE LIKES” arg=“what she likes”/>
<sub name=“HOBBIES” arg=“galleryOne.swf”/>
<sub name=“BLA BLA” arg=“bla bla.swf”/>
<sub name=“BLA BLA” arg=“bla bla.swf”/>
<sub name=“BLA BLA” arg=“bla bla.swf”/>
<sub name=“BLA BLA” arg=“bla bla.swf”/>
<sub name=“BLA BLA” arg=“bla bla.swf”/>
<sub name=“BLA BLA” arg=“bla bla.swf”/>
</item>
<item name=“PICTURES” arg=“pics.swf”>
<sub name=“PICTURES” arg=“pictures”/>
<sub name=“BLA BLA” arg=“bla bla.swf”/>
<sub name=“BLA BLA” arg=“bla bla.swf”/>
<sub name=“BLA BLA” arg=“bla bla.swf”/>
<sub name=“BLA BLA” arg=“bla bla.swf”/>

&lt;/item&gt;

</menu>

I tried putting _root.loadMovie(arg) but it will not load the movie?
I hope this makes sense.
