PPT copy all slides

Hi all,

I tried to write a PPT merge Script for PowerPoint 2004 Mac.
All I need is some help copying all slides and saving the file.
I would be glad if anyone could find my mistake with the saving part and explain how to select and copy all slides of a presentation?

Thanks a lot.
