Batch PDF script works in ID4 but not in ID5.5

Question

this script worked flawlessly in ID4, but doesn't work in 5.5....It's a script that converts all open indd files to pdf.
This is the error...
AppleScript Error!
Error Number: -2741
Error String: Expected "," but found application constant or consideration.
Engine: Default
File: Users/AM/Library/Preferences/Adobe Indesign/Version 7.5/en_US/Scripts/Scripts Panel/PDFer.applescript
Anyone know what's wrong with the script?
This is the script:
property convertSpotToProcess : false
my main()
on main()
  tell application "Adobe InDesign CS5.5"
  set alleExportFormater to name of every PDF export preset
  set alleDok to name of every document
  tell document 1
  set valgtExportFormat to (choose from list alleExportFormater with prompt "Choose PDF Setting")
  if valgtExportFormat = false then error number -128
  set targetmappe to my velgmappe()
  end tell -- doknavn
  set valgtExportFormat to PDF export preset (valgtExportFormat as text)
  repeat with ggg in alleDok
  set doknavn to ggg as text
  tell PDF export preferences
  set page range to all pages
  end tell
  set filnavn to doknavn
  if filnavn ends with ".indd" then set filnavn to text 1 thru -6 of filnavn
  set filnavn to filnavn & ".pdf"
  tell document doknavn
  if convertSpotToProcess then set convert to process of (every ink whose is process ink is false) to true
  set targetfil to (targetmappe & filnavn) as string
  with timeout of 40 * 60 seconds
  export format PDF type to targetfil using valgtExportFormat without showing options
  end timeout
  delay 1
  end tell
  end repeat
  say "Your PDFs are ready. "
  end tell
end main
on velgmappe()
  try
  tell me to activate
  end try
  return (choose folder with prompt "Choose Folder")
end velgmappe

Hi,
Use the ready made script was developed by Peter.  It's one of the good resources, find in the following links.
