Read out certain levels only

[Vera]

:-(

I seem to have cheered too early. :-( Some filteringin E-DataAid
showed that E-Prime is still exactly doing as it likes.

I also had some mistakes in the previous code, here it is again:

Dim nLevel as Integer
Dim TriggerValue as Integer

If (NewTriggerValue > 0) AND (NewTriggerValue < 7) Then
	For nLevel = 1 to DesignList.Size
	TriggerValue = DesignList.GetAttrib(nLevel,"Trigger")
		If TriggerValue = 1 Then
			DesignList.SetWeight nLevel, 1
		Else DesignList.SetWeight nLevel, 0
		End If
	Next nLevel
' 	DesignList.Reset
ElseIf NewTriggerValue = 0 Then
	For nLevel = 1 to DesignList.Size
	TriggerValue = DesignList.GetAttrib(nLevel,"Trigger")
		If TriggerValue = 0 Then
			DesignList.SetWeight nLevel, 1
		Else DesignList.SetWeight nLevel, 0
		End If
	Next nLevel
'	DesignList.Reset
End If

A few remarks to this code:

1. E-Prime is still doing what it likes, guaranteeing me no
counterbalancing whatsoever.
2. I had to add: TriggerValue = DesignList.GetAttrib(nLevel,"Trigger")
- If TriggerValue = 0 Then and I know I could have been doing that
more elegantly (like you did Michiel), but then E-Prime complains that
there are "too many variables".
3. If I add this piece of code, not only will E-Prime still not do
what I expect it to do, but it will also generate blocks as it likes.
Sometimes 3, sometimes 4... But never 7 as it is supposed to do!! In
my last test run it even stopped in the middle of a trial going
immediately to the block feedback! Anybody any idea why that could be?
It seems to me that this piece of script has nothing to do with the
number of blocks or anything.
4. As you can see, DesignList.Reset has been commented out, because
when I add this, E-Prime runs only one trials (instead of 36 in a
normal block) and then goes immediately to the Block Feedback.

I don't understand this program, it makes absolutely no sense to me. :-

Greetings, Vera

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'.
