attachMovie, then goto frame?

I'm attaching a movieClip, and need it to then go to a specific frame.

Here's my code to load the mc:

Code:

---

this.attachMovie("mcSpecialists","mcSpecialists",10);

---

Now, what's the trick to get me over to frame 90? Thanks!

var tempmovie = this.attachMovie("mcSpecialists","mcSpecialists",1 0);
tempmovie.gotoAndStop(90);

or

tempmovie.gotoAndPlay(90)

mcSpecialists.gotoAndStop(90); // should get you there :)

Thanks Gents, both work great.
