Randomization

No, that's one of the problems. I want AB1 and AB4 to randomize with each other and AB2 and AB3 to randomize with each other, but not all of the four randomized together.

I see the problem. You can't have multiple sets of BGR assignments within a single questionnaire. Normally you could break the items up into multiple questionnaires but you have the added difficulty of randomly assigning the instructions across the multiple blocks.
