There may be a better way to do this, but the workflow was created before being handed over to me.
Basically, there is an existing AppleScript to paginate a product in InDesign, but the Paragraph Style Sheet line in AppleScript is very basic & uses the wrong font!
There is an example:

on SetTextStyles()
tell application "Adobe InDesign CS2"
tell active document
try
set firstLineStyle to paragraph style "FirstLine"
on error
set firstLineStyle to make new paragraph style with properties {name:"FirstLine", point size:6, font:"Arial Narrow"}
end try

What this 'firstLineStyle' should relly look like is this (based on the InDesign info):
FirstLine
[Basic Paragraph] + next: [Same style] + BentonGothicCond + Bold + size: 8 pt + leading: 9.5pt + tracking: -20 + pair kern method: Optical + tabs: count = 1, [position: 140 pt, alignment: right]

I get scripting errors when I have tried (still learning AppleScript), things like the 'pair kern method' & 'tab counts' are not well liked.
Can someone tell me what I need to do to get this to work?

Thanks for any help.
