Upgraded to Mavericks now script not compiling

Scripting Forums AppleScript | Mac OS X
#1

I just upgraded from Snow Leopard (10.6.8) to Mavericks (10.9) and have a script that while it runs okay, will not compile in the Applescript Editor.

on run
	tell application "Finder"
		set sourcePath to choose folder with prompt "Please select SOURCE folder:"
		set savePath to choose folder with prompt "Please select DESTINATION folder:"
		set fileList to (files of entire contents of sourcePath) as alias list
	end tell
	
	repeat until fileList = {}
		set FilePath to item 1 of fileList as alias
		
		tell application "Adobe Photoshop CS3"
			open FilePath
			save document 1 in FilePath as TIFF with options {class:TIFF save options, byte order:IBM PC, image compression:LZW} appending lowercase extension
			
			close document 1
		end tell
		
		set fileList to rest of fileList
	end repeat
end run

I get a Syntax Error which says "Expected end of line, etc. but found “{”.

Any thoughts?

Where does the cursor end up when you get that message?

(Apart from a different Photoshop version, it compiles fine here.)

The cursor was at {class:TIFF save options… but actually I was able to now get it to compile fine but having some other issues so I’m going to post the new issue on another thread.
