Read out certain levels only

[Vera]

Ok guys, just to let you know that I am really trying here, a small
update:

Yesterday I tried to solve this problem with nested lists (knowing
that nested lists very quickly get very complicated and taking into
account that Michiel pointed out in his E-Prime doc that the random
doesn't seem to be completely "trustable") but the problem is that I
get to the same thing: I would basically have two lines, 1 pointing to
the condition for trigger 1 and another one pointing to trigger 2. But
then, how to access this line??
I need to figure out some way to tell E-Prime:

If trigger 1 then PLEASE take only line 1

(Or in the old solution, which I very much preferred, because it was
much cleaner - nested lists do have a high "sudoku-effect"):

If trigger 1 PLEASE take any of the lines for which attribute.trigger1
= 1

Down to the beginning again, I don't know how to solve this. :-( Any
ideas are very welcome. :-)

Greetings, Vera
