Editing number of practice sets in n-back task

Hi there! I will be administering the n-back and OSPAN tasks to participants in a longitudinal diary study. This question pertains to the n-back task. As they will be doing the task over 6 consecutive days, we wish to reduce the number of practice sets they do after the first day. I have managed to reduce the number of PracLetter trials (just letter) and PracBoth sets (both the math operation + the letter recall practice trials); however, I cannot for the life of me figure out how to reduce the number of PracMath trials (just the math operation); currently there are 15. I'm sure it is something obvious but I can't seem to figure it out. Thanks in advance for any help!

To reduce the numnber of math practice trials, edit

<list PracMathList>
/ items = (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15)
</list>

I,e., if you wanted only 10 math practice trials, you'd change the above to

<list PracMathList>
/ items = (1,2,3,4,5,6,7,8,9,10)
</list>

Thank you so much for your help! :)
