Export an animated Gif with a movie clip object

Hi Nicktendo, 

thank you for your answer! 

I've tried both the solutions but I can't solve my problem: 

first I tried converting the movie clip in a graphic object without touching its own timeline (which is actually longer than the main stage).

Then I tried to make all the timelines with the same lenght, but still I can't export in an animated gif properly. 

(moreover i need the clip has a slower animation, so I need this timeline be a bit longer than the main stage).

Do you mind if I attach my file here to let you take a look? It s the original file, so you can see first the animation I would like to achieve and then you can tell me what i'm doin wrong.

I would appreciate it a lot!

(try to play the html file first to see both the animations work properly)

Thank You again Nick,

I hope to hear from you soon!

Dave
