counting response types separately then displaing the counts at the end of each block

[kelsey.leigh.carlson at gmail.com]

Hi all,
 In my experiment I have a condition called "Either" in a list object it is 
defined as "Cue" and presents an "E" on the screen to the subject. During 
this condition subjects can press either "n" or "b" on the keyboard. During 
each block I want to count the number of "n" responses and the number of 
"b" responses separately, then present the separate counts in a text object 
at the end of each block. 

I've pasted in the coding I've done here and hope that it makes some sense, 
please feel free to ask me questions if it does not. Here I create counting 
variables "count_n" and "count_b", set them to 0, then set the Attributes 
"total_n" and "total_b"which are scripted so that during the "Either" 
condition when "n" is selected "total_n" should reference "count_n" and add 
one (+1); when"b" is selected "total_b" should reference "count_b" and add 
one (+1). 

In the user script:
' Block choice variable
Dim count_n As Integer
Dim count_b As Integer
Dim total_n As Integer
Dim total_b As Integer 

In FirstTrialITI: (bit of Inline script, I believe it repeats after each 
trial)
count_n = 0
count_b = 0

In TMS: (InLine script that runs a block)
' choice_selection
count_n = count_n +1
count_b = count_b +1

If ((c.GetAttrib("Cue") = "E") And (currentresponse = ("n"))) Then 
c.SetAttrib "total_n", count_n
End If

If ((c.GetAttrib("Cue") = "E") And (currentresponse = ("b"))) Then 
c.SetAttrib "total_b", count_b
End If

I can see in the data file it creates columns for "total_b" and "total_n", 
but it counts them together!

total_b total_n
1 NULL
NULL 2
3 NULL

I also tried this piece of code, but "total_b" and "total_n" were still 
counted together:
If ((c.GetAttrib("Cue") = "E") And (currentresponse = ("n"))) Then 
c.SetAttrib "total_n", count_n
Else If ((c.GetAttrib("Cue") = "E") And (currentresponse = ("b"))) Then 
c.SetAttrib "total_b", count_b
End If
End If

Furthermore, when I try to present the separate counts in a text object at 
the end of each block by typing [total_b] and [total_n] Eprime says "no 
such attribute".

I hope this made some sense, but will answer any questions that you may 
have. Thanks a lot for any help. 
Best,
Kelsey
