Beginner! please help! Movie clip placed on time line not playing!

Hi! if any one could please help me it would be greatly appreciated!

So im trying to make my first website in flash and ive ran into a problem. I have the main movie, my main time line. I have a few animations going on in this that were all created in that main time line. those work fine. however, i created two new movie clips (still inside the same .fla file) and animated them with thier own time line. I then thought you could just drag and drop these movie clips onto your main time line and they would play inside the movie. but when i press ctrl + enter, the dont play!

here are some points of intrest.

my main movie (the main time line) is 130 frames.

the movie clips i made inside the same .fla file are between 400 and 600 frames.

i placed both new movie clips on the 130th frame in the time line with their own layers.

also there is a layer for actions on the 130th that has stop();

i thought that maybe the time line had to be as long as those movie clips i created and so i extended it but they still didnt play.

im thinking action script is involved? please help me im getting pretty frustrated and im sure there is something simple to achieve this.

here is a link where you can download the source files im using. if you open the file the two movie clips i created are called front two and front one and are layers with the same name.

this board wont let me fully post my link cause the last word in it is shit so youll have to type it in your browser. its http://public.me.com/mattshit (just remove the asterisks)

also i noticed that my file is huge. i used photoshop to create everything and them imported it into flash. is there a way i can reduce this size?

thank you sooo much! please help!
