onClipEvent(enterFrame){  
this.\_rotation=this.\_rotation+=50;  
}

You’ve mixed two operators. += is an operator that adds a value to the existing value, while = is an assignment operator.

```auto

anumber = 5;
anumber+=3;
//this is the same as saying
anumber = anumber+3;

```

= operator: [http://www.macromedia.com/support/flash/action\_scripts/actionscript\_dictionary/actionscript\_dictionary041.html](http://www.macromedia.com/support/flash/action_scripts/actionscript_dictionary/actionscript_dictionary041.html)
