Using stimuli based on participant answers

[Tim]

I downloaded the "Study-Recall" example and have been playing with that 
most of today - I can't seem to get it to do exactly what I want it to do. 
As I understand it (and I am a complete novice to programming other than 
reading the E-Basic stuff and practicing a few days with that) E-Prime is 
taking all items sampled for the study session and using the SetAttrib 
method to populate a list for recall.

To use only the items that participants respond to by pressing "1," I have been 
experimenting with some If...Then statements such as this (with StudyWord 
being the name of the stimuli display:

If "StudyWord.RESP" = "1" Then
    RecallList.SetAttrib counter, "Word", c.GetAttrib("Word")
    RecallList.SetAttrib counter, "CorrectAnswer", "1"
End If

I am stuck here - despite trying pretty much everything I can think of I 
cannot seem to figure out how to tell E=Prime to look at the participant 
response. Maybe there a specific thing that I am unaware of to list after 
IF that refers to what the participant enters?

Any thoughts?   Again, any help is very much appreciated!!
