My heading explains my problem. I have added they section of my script with the issue at hand. The document 1 template will save into the filepath and then close correctly, but once Quark tries to open the filepath the error pops up. Any help with this would be great. Thanks

if (exists document 1) is true then

	set workpath to ("" & (path to current user folder)) & "Desktop:" as text
	tell application "QuarkXPress"
		set filepath to workpath & "file.qxp"
		save document 1 in filepath version 80
		close document 1 saving no
		open filepath use doc prefs yes remap fonts no with reflow
	end tell
end if

What does Quark say in the dictionary for open?
