Read out certain levels only

Ok, found a way to be at the experimental setup AND have internet
(whew!!!). ;-)
So the thing I did was:
If (NewTriggerValue > 0) AND (NewTriggerValue < 7) Then
For nLevel = 1 to DesignList.Size
If c.GetAttrib("Trigger") = "1" Then
DesignList.SetWeight nLevel, 1
Else DesignList.SetWeight nLevel, 0
End If
Next nLevel
ElseIf NewTriggerValue = 0 Then
For nLevel = 1 to DesignList.Size
If c.GetAttrib("Trigger") = "0" Then
DesignList.SetWeight nLevel, 1
Else DesignList.SetWeight nLevel, 0
End If
Next nLevel
End If
And now that I could finally connect, I see that you proposed me the
same thing. :-)
And the best thing: it works!!!! Checked the database with E-DataAid
and it's all perfectly balanced. :-)
Thanks a lot for giving me the idea!
Have a great weekend!

In fact, I think I might have misstated that nested-lists are untrustworthy - in general, people are much more prone to making errors than computers, and indeed, this to me is the main problem of nested lists. I do, however, use them all the time, myself, but usually not for my main 'triallist'.
