Hi runew,

do you want the document start with a different page number?

Hi Loic,

InDesign CS3 has no property startPageNumber with documentPreferences .

Example for CS3 (the screenshot is showing InDesign CS3):

Document starts with page number 5.

You want to start with page number 3.

Code for that:

// Number to decrement:
var nDecrement = 2;

// pageNumberStart for a section is only valid, when continueNumbering is set to false
app.documents[0].sections[0].continueNumbering = false;
var myCurrentNumber = app.documents[0].sections[0].pageNumberStart;

if(myCurrentNumber>nDecrement+1)
{
    app.documents[0].sections[0].pageNumberStart = myCurrentNumber - nDecrement
};

If there is more than one section in the document, you have to add code.

Note 1: You could change continueNumbering to true afterwards.

In case you are using the documents as part of an InDesign book file and continue numbering is required.

Note 2: Every InDesign document has at least one section. The one that starts on the first page of the document.

var ps = app.activeDocument.documentPreferences.startPageNumber;
if (ps<3) {
     alert("Can't decrement pages sorry :(" );
}
else app.activeDocument.documentPreferences.startPageNumber -= 2;
