exporting multiple files problems ....

Hi all
Im working on an a project where I will need to export a collection of curves as separate illustrator files(.ai)

I have attached a example file which has all the elements that i will use in the file, the problems that i have encountered are in the VB component

As some of you may notice i have incorporated the example posted up by Marc Hoppermann, which was tweaked by Damien Alomar.

I think what essentially is happening is that the curves are being overwritten and only the last curve is being exported properly. This is a bit strange as i have played around with the script before to export different file types and it had worked fine.

Hopefully the mistake im making is pretty simple , so if anyone could help that would be much appreciated.
Thanks also Vicente Soler, who gave me some help on the data tree part of this file.

Cheers

Louis
