I tried using a working document and it would go to section instead of page.
when I use a blank document with lets say 5 pages, it always went to page 1.
I used several different lines of code and they all went to page 1 on the blank document;
WordApp.Selection.Goto What:=wdGoToPage, Which:=wdGoToNext, Name:="5"
WordApp.Selection.Goto What:=wdGoToPage, Count:=5
WordApp.Selection.Goto wdGoToPage, wdGoToNext, , 5
does it work with you?
