Hello,

This is a newbie question (and so am I) but i havn´t found the answer anywhere and I would gladly appreciate som help!

This is what I am trying to do:

function loadXML(loaded) {  
if (loaded) {  
xmlNode = this.firstChild;  
image = [];  
description = [];  
total = xmlNode.childNodes.length;  
for (i=0; i\<total; i++) {  
[COLOR=Red] image\* = xmlNode.childNodes\*.childNodes[0].firstChild.nodeValue;  
description\* = xmlNode.childNodes\*.childNodes[1].firstChild.nodeValue;  
p = image\*;[/COLOR]  
}  
firstImage();  
} else {  
content = “file not loaded!”;  
}  
}

[COLOR=Red]trace§

[COLOR=Black]how come p is undefined? is there a way to make the variable global and useable outside the function?

I am basically trying to use the tutorial for loading external pictures from an XML file found here on kirupa, and get it to assign a number to every picture and load the latest addition.

So when a PHP program updates the XML file, the flash will load that latest added picture.

Thank you very much for your help and time!
