I have created a new class called Line that extends the MovieClip class in a external .as file.
The class Line has a variable in it called XVal. (i used var XVal:Number; to declare)
I then created an instance of this using the line:
attachMovie(“Line”, ‘line1’, 100);
If i want to access the value of XVal from the instance line1 on the main timeline what syntax do i use?
cheers!
Dave

you need to know that attachMovie returns a reference to a movieclip… so you can simply do…
```auto
var line1 = attachMovie("Line", "line1", 100);
trace( line1.XVal );
```
Take Care
