You could do the stop frame in script.
If(mc._currentfame == 20) {
this.mc.stop();
}
But listen to them about the enterFrame. I learned the hard way too
and what they are telling you is the right way and best way for you.

Try:

The myLeftHand method is being called when an event fires, so the

must be passed in as a method parameter. "Event=null" allows the
event
to be optional - so you could also call it without dispatching an
event.
This worked.
Yes, but just be aware that this technique works for this case, but
would make your code more complex if your event handling function
actually used the event parameter. Personally I would avoid this
technique for event handlers.
Whomever told you to use enterframe to have something happen on
frame 20
made a mistake. It's a valid way to get it working, I personally
think
an enterframe loop is a waste of resource for that case and, more
importantly, I just don't think you're there yet. Go back to
putting an
action on the timeline at frame 20.
You have a good point, of course. But I am going to do this anyway.
I will
be calling this mc many times. Besides, I firmly believe that the
"right"
way to do this is calling the event as I enter frames.
It's not the right way for this situation.
Enterframe operations are expensive. The more code that the flash
player is executing the greater the load on the processor. For the
trivial example that you have, it doesn't matter, but generally
think hard if enterframe is the right solution.
In this case you are needlessly "watching" a movieclip to stop it at
frame 20, when you could simply add a stop action to the timeline.
Since that's all that you need to have the movieclip do, there's
utterly no point in making life complicated for no reason. If you
had a sophisticated behaviour (say stopping the movieclip at an
arbitrary frame), I might have some sympathy with the approach, but
otherwise it's complication for no reason. I have used the technique
on imported MovieClips that I have no access to, so it's a useful
technique but totally unnecessary here.
In programming in general and flash in particular, simplicity is
preferable to complexity. Only make things as complex as they need
to be for the job and no more. There is a much mentioned anagram:
KISS - Keep It Simple Stupid, which makes the point most eloquently.
Frame 20 awaits your stop() command.
I think you may be learning some more things about flash but may be
picking up bad habits already.
