Nested List Not Following Selection Rules

[Noam Schneck]

Hi Sally,

Thank you for the response.  Sorry for the e-prime version elitism.  I 
can't downgrade because I don't have the lower version and would need to 
reprogram the entire task if I did. I am attaching here an edat file 
extracted into an excel spreadsheet. If you look at columns DB-DK you will 
see the words that were selected for each trial.  Columns DD and DE  show 
the alternating blocks.  What this file shows is that for the first six 
blocks  there are no repetitions and then in blocks 7 and 8 (rows 153-200 
on the excel spreadsheet) there are repetitions (highlighted in pink). The 
problem is that these repetitions occur within one block. I can't figure 
out why that is happening since I set the wordlist to random. I don't mind 
if the repetitions happen across blocks but I can't have them within blocks.

Let me know if you have any further thoughts,
noam
