resetting the sampling of a nested list

Hello,

I am currently having trouble with the sampling of a nested list that
contains more items than the list calling on it. Here is the basic
setup:

DetailTestList1: 150 items. Each row contains a description of a
picture and 6 true/false detail pairs (details are matched such that
pair 1 has a true column and a false column, and so on). This list is
randomly selected and calls on DetailTestProc which contains the list
below.

DetailList1: This list takes the sampled item from above and selects
one detail from each pair sequentially until it works through 6 pairs.
Each row corresponds to a detail pair the will be displayed on a
slide. We would like for it to randomly present either the True or the
False detail with one constraint: one type of detail (True or False)
can only be chosen a minimum of 2 times and a maximum of 4 times for
each item selected from DetailTestList1. The DetailPair field is
filled in by a nested list to determine if a True or False detail is
chosen, and this in turn grabs either the True or False pairmate from
the list above which is displayed on a slide. In order to do this, we
nested the following table:

TrueFalseList: This list has 8 rows, 4 True and 4 False. We'd like the
list above (DetailList1) to sample 6 of these 8 rows and then reset.
Ideally, Each selection from DetailTestList1 would move on to
DetailList1 where 6 details are presented. Whether or not they are
True or False depends on sampling 6 items from TrueFalseList. This
completes the loop and another item from DetailTestList1 can be chosen
with the sampling from TrueFalseList reset.

Unfortunately, TrueFalseList seems to be sampled 8 times, even when I
set it to reset/exit after 6 samples. Any ideas on what parameters or
set-up I should change?

Thanks for your help,
Jeremy
