All,  
I have the following code to populate a dynamic text box:

```auto

myData = new LoadVars();
myData.onLoad = function() {
trace ("The text box before autosize is: " + sailing_txt._height);
sailing_txt.htmlText = unescape(this.myVariable);
sailing_txt.autoSize = true;
trace ("The text box after autosize is: " + sailing_txt._height);
}; 
myData.load("sailing.txt");

```

The output of this is:  
The text box before autosize is: 388.25  
The text box after autosize is: 712.5

My problem is that I need to get the autosized height instead of the regular height of the text box before autosize. In a parent movie clip I have the following code to do some custom scrolling:

```auto

contentHeight = _parent.scrolledMC.sailing_txt._height;
trace("The content height is: " + contentHeight);

```

The output of this is:  
The content height is: 388.25

So it’s getting the size of the text box before it’s autosized. How can I fix this?

Thanks in advance!
