Hello, All was working well until the xml changed. Sometimes the **c\_Result** node in the xml doesn’t exist and my **c\_points** text box returns ‘ **undefined** ’. I don’t know how to leave the c\_points text box blank if the c\_Result node doesn’t exist and load it if it does.  
I have read loads of posts about this and have tried adding:  
if(point != undefined){  
} else {  
c\_points.text = “”;  
}  
But that doesn’t work, does anyone know the answer to this please?

**AS2 CODE**  
import mx.styles.CSSStyleDeclaration;  
\_global.styles.TextArea = new CSSStyleDeclaration();

\_global.styles.TextArea.setStyle(“backgroundColor” , “transparent”);  
\_global.styles.TextArea.setStyle(“borderStyle” , “none”);  
\_global.styles.TextArea.setStyle(“html”, “true”);

var str:String = “”;  
var k:Number = 0;  
var tmp:XML;  
function loadXmlResults(){  
xmlNode = this.firstChild;

```
str = (String(xmlNode.childNodes[1].firstChild)).split("&lt;").join("&lt;").split("&gt;").join("&gt;").split("&quot;").join("\"");
tmp = new XML(str);
_country.text = tmp;

str = (String(xmlNode.childNodes[2].firstChild)).split("&lt;").join("&lt;").split("&gt;").join("&gt;").split("&quot;").join("\"");
tmp = new XML(str);
_driver.text = tmp;

str = (String(xmlNode.childNodes[3].firstChild)).split("&lt;").join("&lt;").split("&gt;").join("&gt;").split("&quot;").join("\"");
tmp = new XML(str);
_constructor.text = tmp;

```

}

xmlResultFinish = new XML();  
xmlResultFinish.ignoreWhite = true  
xmlResultFinish.onLoad = loadXmlResultFinish;

var rank, person, countr, point:String = “”;

function loadXmlResultFinish(){  
c\_rank.text = “”;
