Simple rollover question... help!

whenever something like this happens, i feel dumb, because it seems like the answer is sitting right in front of me but i can’t just figure it out!

i’m not sure why my fade in-and-out rollover is acting up. it worked fine for the first button, but on the next few it only performs the rollover or rollout action.

you can see my problem here: http://sonmi.150m.com/aromaticoasis/02.swf

(it’s stretched out and not tweaked at all… but you get the idea)

the fla is located here

thanks in advance for any help.
