displaying response count at end of block

[free_operant_task]

Hi Kelsey, 

Have you defined the attribute globally on the user tab of the generated 
script? To count across multiple blocks or reference the counter variable 
at the highest level of the task, you need to define the variable on the 
user tab of the script. I can send an example scirpt where I have used 
counter variables like these, if you like. 

Hope this helps, 
Holly
