Exactly what do I need and where do I need it for this Action Script to work.

I am a pretty decent flash designer, but I have always avoided Action Script because manuals don't spoonfeed enough for me to even get started.  So now I'm just going to dive in the only way that ever works for me, which is EE!

I got this AS from another question and if I could see it work I would then at least know what questions to ask on EE to start to understand it.

So please, exactly what do I need in the way of movie clips and other elements for it to work? For example,  what kind of movie is "Letter"? A movie clip? An AVI/   Is there a difference between "Letter" and "letter"?  Is MC_point a movie clip or an instance of a movie clip o both?  ?  Where should it be?
Does this action script go in a frame? What frame? etc., etc. You can't dumb it down too much for me!

Here's te link to the original question: http://www.experts-exchange.com/Software/Photos_Graphics/Web_Graphics/Macromedia_Flash/Q_21649018.html

Thanks!

MC_point.onLoad = function() {

      // constants

      textStr = "Teach Yourself ActionScript!";

      letterSpacing = 16; // how far apart the letters are

      startX = 50; // horizontal position of leftmost letter

      startY = 200; // vertical position of letters

      startScale = 600; // how big the letters start

      scaleStep = 50; // how much the letters shrink per frame
 

      // create all movie clips

      for (i=0;i<textStr.length;i++) {

            this._parent.attachMovie("Letter","Letter"+i,i);
 

            // fill with letter

            this._parent["letter"+i].letterText = textStr.charAt(i);

            // move off screen

            this._parent["letter"+i]._x = -100;

      }
 

      // init variables

      letterNum = -1;

      scale = 100;

}
 

MC_point.onEnterFrame = function() {

      // if scale is 100, then time for next character

      if (scale == 100) {

            letterNum++;

            

            if (letterNum >= textStr.length)

            {

                  trace("No more loose end...  Good bye!!!");

                  delete this.onEnterFrame;

            }

            // set position of next character

            this._parent["letter"+letterNum]._x = startX + letterNum*letterSpacing;

            this._parent["letter"+letterNum]._y = startY;
 

            // set to largest size

            scale = startScale;

      }
 

      // make a little smaller

      scale -= scaleStep;

      this._parent["letter"+letterNum]._xscale = scale;

      this._parent["letter"+letterNum]._yscale = scale;

      

      trace("letterNum = " + letterNum + "   textStr.length = " + textStr.length);

}

Hi there John, MC_Point will be the instance name of a movieclip.
difference between Letter and letter - yes Flash AS is case sensitive.
this code can go on the timeline where the movieclip resides.
also the parent of this clip (assuming the root) - has a bunch of clips as well, letter1, letter2 etc.
hope that helps.

Hi blue-genie,

OK, my flash file has one layer and one frame. On that frame  I have named the instance of my MC "MC_Point". I have put the code in that frame. I'm afraid that now I need the next 3 or 17 steps/elemnts spelled out exactly for me to see anything happen!

Thanks!
John
