help needed

[alp115]

Thanks Tim.

I am having trouble with this line:

RecallList.SetAttrib counter, "Word", StudyList.GetAttrib (unsampled,
"Word")

Actually I am trying to design a similar experiment where some images
the Triallist will be presented first and later along with some novel
images (which were not shown in the block) are presented in a rating
block.

I have modified the code as follows:

Dim i As Integer
Dim novel As Integer

For i = 0 To 1
	'Choose levels until get a novel level
	Do
		novel = Random(1, TrialList.Order.Count)
	Loop Until  TrialList.GetAttrib(novel, "Old") <> "1"

	'set the new sample as old
	TrialList.SetAttrib novel, "Old", "1"
Debug.Print novel
	'add the level to RateList - increase counter to add levels
	counter = counter + 1
	RateList.SetAttrib counter, "image", TrialList.GetAttrib (novel,
"image")

Next i

RateList.Reset

The following Runtime error occurs after the trial block:

Factor error: Level specified is not valid in RateList

Can you give some insight about this error.

Thanks very much,
Asma
