Thanks, using this works fine (mostly),

Except when I have multiple Players with the same name in the project. For
example if I have a Player with the ExternalName 'Cat' on page 1 and another
Player with the ExternalName 'Cat' on page 2.  Then execute the script on
Page 2 the 'Cat' on Page 1 moves forward. (Note: in playing around with this
at one point the 'Cat' on page 2 did move, but when I renamed the 'Cat' and
made a new one it went back to the behavior where the 'Cat' on page 1 moved

I changed the script to refer to 'Page' instead of 'ActiveWorld' and that
seemed to solve the problem, until I duplicated the page (which causes 'Cat'
to become 'Cat1') and then renamed 'Cat1' to 'Cat' then the 'Cat' on the
previous page moved.

So is there anyway to specify the 'search order' for players where it looks
in its current ?World/Playfield? first?
Of course the simplest answer may be for me to avoid the problem and not use
books ;)
