I have a project due in a week, and I’m lost! :\*(  
I’m having a lot of troubles with action script since most of the project is based on self learning. :puzzled:

Part of the project is a game attached to an interactive representation of the blood components for children (it’s a very minimal representation).  
The game consists of 4 objects, one of them is player controlled (WCell), and the other 3 are supposed to randomly fall -top to bottom-, the player gets points for “eating” the correct object(germs), and loses points for eating the wrong objects(tasiyot\_MC & RCell\_mc).

## I’m attaching the code (also zipped fla file) here, hoping that someone in this huge forum could help me find out why am I receiving this error:

## TypeError: Error #1010: A term is undefined and has no properties. at MethodInfo-2() :ponder:

Thank you much in advance! 😃
