I am working on a BIG book 700+ pages. It was originally created in Quark. I need to complete production in InDesign. I am looking for a way to streamline the conversion process using AppleScript. I am learning the basics but am running into problems in the open file stage!

tell application "InDesign 2.0.2" to activate
 open file "PowerBook G4:Users:michael:Documents:Current Projects:x:x:x"
 tell application "InDesign 2.0.2"
         save document "x" in file �
                 "PowerBook G4:Users:michael:Documents:Current Projects:x:x:x"
         close "x"
 end tell

In AppleScript I get the Alert: Could not run the script because it is not scriptable.

Does anyone know why? (I see the "open" comand in the InDesign Scripting PDF)

Also any tips on opening closing saving then opening another document and doing the same in succession would be useful.

Thanks
