Try something like:
tell layout window 1 of MyDoc
set active page to page 1
You're right -- this is a case where using tell causes problems. You can use this form:
set active page of layout window 1 of document 1 to page 3 of document 1
Otherwise you nedd to use a reference:
set thePage to page 3 of document 1
tell layout window 1 of document 1
set active page to thePage
Thanks sstanleyau, That worked!
set active page of layout window 1 of MyDoc to page 1 of MyDoc
I was pleasantly surprised that it still went to the first page, even if my docs section started with page 2.
