Tobias,
Thank you for your response. I am currently using a nested list
containing my 23 distractors and one probe word. I have my main list
calling to that for each presentation, my problem is that I cannot
figure out how to guarantee that my probe word will show up every time
while still keeping where it shows up in my list random.

Thanks,
JCFIII
