QuarkXPress 6 Scripting Problem

I’ve been looking for someone to answer this question for me …so here goes

for some reason i cannot change the page height of any documents in QuarkXPress 6 via applescript I was just wondering if you have been able to successfully do this? If so, how! I’m currently working on converting a script i wrote for v4.11 to 6.0 and this is really bugging me! neither of the scripts below work! …they don’t give errors either …it’s just like they are ignored.

SCRIPT 1…
tell document 1
set newPageHeight to (page height as real) * 2 as real
set page height to newPageHeight
end tell

SCRIPT 2…
tell document 1
set page height to “7"”
end tell

any help would be GREATLY appreciated
