[FMX04] preloader question

programming flash
1

Greetings,

I’ve got some preloader action script that I would appreciate someone to look at.

It is currently set to cause the target clip to play after the load is 100% complete. I want the clip to begin after only 20% has downloaded.
Unfortunately its not at all the normal method that I use when creating my own preloaders so I’m lost.

thanks!
