Reply To: package for output – single pages, from a multi page document

Ari
I have installed and run your script but I get this error message:

Error Number:21
Error String : null is not an object

Engine: main
File: /users/jodie/Library/Preferences/Adobe Indesign/Version 11.0/
en_GB/Scripts/Scripts Panel/AutoPackage.jsx
Line: 90
Source: newMaster = srcMaster.duplicate(undefined,
newDoc);

Have other people had this? how can I resolve?
Many thanks!
