Changing a preference in Quark using GUI scripting

Scripting Forums AppleScript | Mac OS X

Hello,

sorry-I meant to delete my first post and it deleted everything…so posting again

I have a script I started where I want to make sure that a specific check box is checked in one of the quark preferences. Since this one is not in the dictionary, I feel I can use GUI scripting to do it, but I don’t knowmuch about that. . This is what I have so far, which compiles, but doesn’t work.

tell application "QuarkXPress"
	activate
	tell application "System Events"
		set "Standard Em Space" of "Preferences" to true
	end tell
end tell

Here is the message I get when it fails:

Can’t set “Preferences” to true. Access not allowed.

I know I am missing steps, but this is the one preference am trying to keep on when I open every quark document.
Ultimately, I would want to drag it onto the script and have this happen once the document opens.

thanks and again, sorry for the repost…
