Hello,  
I’m trying to take variables from an external php file and load them into flash. I got most of it working, however i’v ran into a few issues with passing my variables around.

First I declare my global vars on the first keyframe:

```auto

onLoad()
{
_global.thedata = new Array();
_global.anum = 0;
}

```

Then I run my copy function

```auto

onEnterFrame()
{
getdata();
sites_txt.text = _global.thedata[1];
}

```

```auto

function getdata()
{
	l = new LoadVars();
	l.onLoad = function() 
	{
		
	for(i=0; i<15; i++)
	{
                 _global.thedata* = this["result"+i];
           }
}

```

I am able to confirm that the output from this[“results”+i] is correct. I’m also able to check its entering the array \_global.thedata\* correctly (if I run some test after the for loop). However, in its current form setting the text box with the value of thedata[1] (after getdata() function) doesn’t appear to be working. All I get is a clear input or sometimes an undefined. Could it be that \_global.thedata\* = this[“result”+i]; is passing by reference, thus when the function scope deallocates, the original variables are deallocated with it. Is there a way to pass-by-value? or is there something else i’m missing.  
Please come be my Link! 🔗  
Thanks! 🙂

Hey One\_way\_7

\_global doesn’t exist any more in AS3  
try this link: [http://greenethumb.com/article/11/global-variables-in-as3](http://greenethumb.com/article/11/global-variables-in-as3)

Thanks! Unfortuantly, it looks like I posted this in the wrong spot. I’m using AS2.0
