Jim,

I just tried setting up a little arrows object and here is what I had 
to do:
- use the object library to place the little arrows in my stack
- create a field, I called it "Numbers" and put a starting number in it 
e.g. 1
- set the cTargetField property of the little arrows object to Numbers 
(the name of my field)
- edited the script of field Numbers to include an empty "closeField" 
handler.
- added 2 new custom properties to the field "Numbers": cMaxValue (10) 
and cMinValue (0)

After that, the arrows all worked fine. if you want a sample stack, 
just let me know.

Cheers,
Sarah
