Combining RBG and OmitConditions (case 6145)

[lisken]

Out of 12 possible sets of questions, I am assigning subjects in each of 16 conditions a particular set of 6. These 6 sets should be presented in random order.

I've used omit conditions for each line of each set to exclude it for particular conditions.

I've used rbg to assign each line of each set the number of the set (1 for the first group, 2 for the second, all the way through to 12 for the last).

But whenever I run this questionnaire, I receive each of the 12 question sets in the order they're listed in the questionnaire. Thus, neither the omit conditions or rbg function is working.

Would very much appreciate any tips!
