What if you assign the first and second questions the same WGR values. And also assign them the same BGR values. As of v2006.1.31, you can indicate a skipto value like +1, +2 etc. indicating how many items to skip rather than a specific variable name.

MediaLab will automatically skip that many items without needing to know the name of a "skipto" variable--it will simply resume wherever it ends up. This is especially nice when the item being skipped to might be randomly determined.

So for the first of the two questions you could assign a +1 skipto value for the option which should skip them over the second question.

Does that help?
