hello,

I want to Linkage one MC in my library. So I wrote  
In **Class** zPlayerClasses.contoller,  
In **Base class** flash.display.MovieClip

My class contoller is located in folder zPlayerClasses, and it is in the main directory (with .swf).

this is my class script:  
[AS]package zPlayerClasses{  
public class contoller extends flash.display.MovieClip {  
public function contoller():void {  
trace(“contoller class instance”);  
}  
}  
}[/AS]

After compile output this error, why?

1017: The definition of base class MovieClip was not found.  
5000: The class ‘zPlayerClasses.contoller’ must subclass ‘flash.display.MovieClip’ since it is linked to a library symbol of that type.

The some error come after change **flash.display.MovieClip** to \*\*MovieClip \*\*
