URGENT - Please help

Please help.
I have a movie within a movie.
When playing the movie (dna1) separately, it plays perfectly. But when I put it all together it won't play.
Please could someone help. I need this urgently!!

Hi Anthea,

**** dna frame1
for (i=2; i<30; i=i+1) {
duplicateMovieClip("dna1",["dna"+i], i);
this["dna"+i]._rotation+=10*i
this["dna"+i]._y+=13*i
}
dna1._visible = 0

**** dna frame2

for (i=2; i<30; i=i+1) {
this["dna"+i]._rotation+=3
}

Hi Poden

I tried what you gave me, but it isn't working.
Please could you see what I've done wrong.
I attached my file again.

Thanks

Hi Anthea,

Try copy->pasting the code I wrote for frame 1.

for (i=2; i<30; i=i+1) {
duplicateMovieClip("dna1", ["dna"+i], i);
this["dna"+i]._rotation += 10*i;
this["dna"+i]._y += 13*i;
}
dna1._visible = 0;

Then it should work like a charm

Thanks Poden
It plays until it pastes each dna strand but then doesn't continue to play. What do I do now to get it to carry on playing.
