select only one level in a list ? help

[David McFarlane]

Not the solution I had in mind, as it requires more code than the 
Counterbalance approach -- i.e., in the List property pages set the 
List Order to Counterbalance and Order By to whatever (e.g., 
Subject), then use inline code any time before List1 to override the 
Order By, e.g.,

Set List1.Deletion = PickOne(c.GetAttrib("mynumpermutation"))

Admittedly, this is not officially documented, and you can only learn 
this sort of thing by looking at the generated source code and hacking with it.

So your solution does the job just as well and I am glad that it 
works for you.  It also, I admit, opens the way for other possibilities.

Thanks for posting back with your solution,
