Help w. timeline controlled mcs

1

I’ve been successful controlling my movie clips from the main timeline however I recently entered a text movie clip into the timeline and I cannot figure out for the life of me how to control the movie from the timeline. I can get it to play, but the movie stops there.
I’ve been using:

stop();
_root.gotoAndPlay("framelabel");

but with the text effect where it uses so much AS I dont know what to put to make it continue on to the next frame label when its completed.

stop();
//
textvar = textvar.split("");
//
this.letter_mc._visible = false;
//
numberOfLetters = 0;
Xsetter = this.letter_mc._x;
thisTimeline = this;
//
buildLetters = function () {
 if (numberOfLetters<textvar.length) {
  //
  duplicateMovieClip(letter_mc, "letter_"+numberOfLetters, numberOfLetters+1);
  //
  thisTimeline["letter_"+numberOfLetters].shadow_txt_mc.textbox.text = textvar[numberOfLetters];
  thisTimeline["letter_"+numberOfLetters].top_txt2_mc.textbox.text = textvar[numberOfLetters];
  thisTimeline["letter_"+numberOfLetters].top_txt_mc.textbox.text = textvar[numberOfLetters];
  // 
  thisTimeline["letter_"+numberOfLetters].shadow_txt_mc.textbox.autoSize = true;
  thisTimeline["letter_"+numberOfLetters].top_txt2_mc.textbox.autoSize = true;
  thisTimeline["letter_"+numberOfLetters].top_txt_mc.textbox.autoSize = true;
  // 
  thisTimeline["letter_"+numberOfLetters]._x = Xsetter;
  // 
  Xsetter += thisTimeline["letter_"+numberOfLetters].top_txt_mc.textbox._width;
  numberOfLetters++;
  // 
 } else {
  clearInterval(letterInterval);
 }
};
//
letterIntervel = setInterval(buildLetters, 110);

I’ve defied the pass variable and just freeformed my text in on the MC frame AS. if someone could help me figure out how to make this movie perhaps, onClipEvent.stop and go to the designated frame label I’d really appreciate it. Thanks!
