Loop???

i made a banner (header for my site) of 12 frame.

i would like to loop fram 8-9-10-11-12 how do i do that?

tween is set for 1 sec

its ok i found a way anyway..... in the action scripts i put on last key frame 12 to go back to key frame 8 and to play, so it always loop between 8 and 12 just wut i needed.
