Reset a variable and dynamically delete instances on stage

Hi,

http://www.spgmediadesign.com/banners/delayeddisplay(3).zip

I have a banner animation creating a duplicated tiled pattern.

But when the MAIN STAGE animation loops and starts again the boxes continue on - instead of starting again from 0.

I want the boxes to start duplicating again from scratch at the beginning of the MAIN timeline animation.

I presume it will have to
reset the variable
and/or
dynamically delete the instances on stage.

I don't want to use window.location.reload(); as I don't want the WHOLE page reloading.

The boxes have to be created in the same way as the attached.

Would be much appreciated.

Cheers

James
