Vera,

[Took me awhile to get to this because I had other business to attend 
to and I wanted to write this up properly.]

As to "counterbalancing" on attributes other than Group, Subject, and 
Session...  As I hinted in the thread at 
http://groups.google.com/group/e-prime/browse_thread/thread/26d2e1e83c6a09bb 
, although the E-Studio GUI allows options only for Subject, Session, 
and Group, you may "counterbalance" on any other attribute simply 
through a proper application of inline code before the List runs, e.g.,

Set List.Deletion = PickOne(c.GetAttrib("AnyAttribYouLike"))

In fact, List.Order does not have a "Counterbalance" option -- 
instead, Counterbalance in E-Studio just generates a combination of 
settings that makes EP pick a numbered row from the List at runtime 
and run just that, once.  The best way to see this is to use 
Counterbalance in E-Studio and then look at the generated code (and 
IMO if you do not care to look at or understand generated E-Basic 
code, then you should leave this work to somebody else who 
does).  For the record, and to spare you the trouble, here is an 
example of the relevant generated code from the InitObjects subroutine:

Set List.Order = New SequentialOrder
Set List.Deletion = PickOne(c.GetAttrib("Subject"))
List.ResetEveryRun = True
Set List.TerminateCondition = Samples(1)
Set List.ResetCondition = Samples(1)
