Linking Movie Clips together

Hi. New here and new to ActionScripts. My task, I believe, is a very simple one.

How do you link multiple movie clips together on the main stage to play one right after the other?

I have 3 individual movie clips I created (about 100 frames long each clip). What I’ve done is drag movie clip #1 and placed on the main stage in frame one. I then went ahead a dragged movie clip #2 and placed it in frame two and continued this process for clip 3.

I thought, when I tested my movie, it would just play the movie clips in order. However, it just loops clip 1 over and over again, never moving on to clips 2 and 3.

So how do I fix this?
