Tween class import not working in MX?

programming flash

Hi everyone, I just went over the motion tween tutorial for Flash MX, and every time I try to run the code, it pops up

**Scene=Scene 1, Layer=Layer 1, Frame=1: Line 1: ‘;’ expected
import mx.transitions.Tween;

Scene=Scene 1, Layer=Layer 1, Frame=1: Line 2: ‘;’ expected
import mx.transitions.easing.*;**

Can someone tell me why it’s not working? Thanks.
