BGR and WGR Trouble

Hi,
I'm working with a questionnaire in which I have 5 groups, each of which has 60 "questions" to be presented. Within each group, I have the 60 questions broken up into 2 groups. I do not care which order the 5 groups of questions appear in, as long as each's 60 questions are asked before moving onto another group.

I tried using numbers 1-5 in the Between Group Randomization column. Then, within each of the 5 groups, I broke up each set of 60 questions into "1"s or "2"s.

When I run it, after having saved it as an experiment, I get what looks like complete randomization, or randomization within groups (by "1"s and "2"s but I cannot be sure because of the sheer number).

In case I simply got the meanings of WGR and BGR confused, I tried switching the values from one column to the other, but still I get randomization that is not contained with the 1-5 groups.

How can I randomize as I am hoping to?

Not sure about your design. The BGR idea for the 5 groups of 60 makes sense. In what way do you need the items broken into 2 groups [I]within[/I] the larger groups? You had two sets of 30 within each group of 60--both randomized, right? If so, did you [I]always[/I] have 30 WGRs of [I]1[/I] and 30 WGRs of [I]2[/I]? If so, the problem may be that you need to use 3's and 4's for the second group of 60, 5's and 6's for the one after that and so on. Otherwise [I]all[/I] the items with a WGR of 1 across all of your big groups will be randomized with each other and I don't think you don't want that!
