**ERROR:1119: Access of possibly undefined property contact\_mc through a reference with static type flash.display:DisplayObjectContainer.  
\*\*  
I am trying to figure out why I get a 1119 display object error when I use:  
 parent.contact\_mc.alpha = 1; \*\*  
Trying to access a movie clip from another movie clip.  
When I use:  
 MovieClip(parent).contact\_mc.alpha = 1;  
or  
MovieClip(root).contact\_mc.alpha = 1;**  
Get no error but my movie clip contact\_mc does not appear.

\*Strict mode is turned on

Any help or advice would be fantastic.
