Help a newbie with her timeline

(Something to keep in mind: I learned Flash 7 a few years ago (quite in depth,
actually) but forgot it all. Just recently, I have picked up a tutorial book
and have kind-of gotten back into it. I know the basics, but be gentle in your
advice.)

I need help! I have created an interactive flash animation on our company's
landing page that shows you how the product exercises the muscles. I am having
trouble with my timeline, I beleive.

Check it out here, bottom of right column:

Ideally, what I want to happen is the individual movie clips will spin and
then stop. Once you click on them, it will show you a close up of a figure and
highlight what muscles that exercise uses. Then, once you click on the next
exercise, the one you were on will go back to a static (non-spinning) image of
the exercise and will stay that way, no matter whether you skip around or go
from first to last exercise (this only makes sense if you look at the above
link).

Right now I have one flash file that contains 4 movie clips/buttons (each of
the exercises).They are in their seperate layers in the first frame. In each
layer, there is the first movie clip (spinning) in frame 1; in the next frame I
have the movie clip that highlights the muscle groups which plays once you
click on the first movie clip. Directly after this, in the next frame, I have a
button/jpg of the original exercise that does not spin, but when clicked will
take you to the highlighted movie clip. The frames are stacked, so that each of
the highlighting clips are one frame further down the line than the layer on
top of it, so they don't play at the same time.

Therein lies my problem. For example, if you click on the last exercise, then
click on the second exercise, the exercises beneath it spin because on the
second layer, the highlighting movie clip is on the same frame as these movie
clips' spinning image (if that doesn't make sense, let me know and I'll show
you an image of my timeline).

What I need help on is how to keep this from happening. Again, this all might
not make much sense, but please ask me if you need further clarification.


ANY ideas?
