Quote - ... I've tried the ScaleAll1.py.doc you kindly offered, aaaaand: Traceback (most recent call last): File "", line 10, in ? AttributeError: 'module' object has no attribute 'DialogSimple'

Please ignore ScaleAlla.py it was for informational purposes only.

As your getting the error mesage your are, I think you have PP or P5.
This means that you'll need to edit the script as follows :-
replace scaleAmt = poser.DialogSimple.AskFloat("Enter the value you'd like to Scale to:")

with scaleAmt = some number between 0.0 and 1.0

where the number is the %value you want would dialup in Poser divided by 100. Editing the script each time you want a different value will be necessary (adding a Tkinter GUI for this is not really worth the effort).
