CS2 Collect for Output - Adobe Indesign

Maybe what is a problem is the way you manage your package creation and closing the document.
As you close the doc while incrementing from 0, the index of the next doc is always changing and the last index is not present anymore. So when the script try to reach this one it will fail.
In this kind of cases, it's good to decrease from max to zero
so you should have :
for (i = bb.length-1; i >= 0; i--)
etc.
so when you close for example bb[26], bb[25] is still accessible.
Hope it helps.

Thanks Loic

It works, but when I am collecting output files I want to create seprate folder for each chapters. Finallay I the folder structure will be like this

Indesign book
book1.indb
ch01.indd
ch02.indd

Root Folder
ch01 Folder
ch01 package files
ch02 Folder
ch02 package files

Thanks

Try this,
I couldn't test it here
var myFolder = Folder.selectDialog("Please select a folder");
for (i = bb.length-1; i >=0 ; i--)
{
app.open(bb[i].fullName);
var mychapterfolder = new Folder(myFolder.fullName + "/"+bb[i].name)
mychapterfolder.create();
app.activeDocument.packageForPrint (mychapterfolder, true, true, true, true, true, true,true);
app.activeDocument.close;
}
