Build Matrix based on previous multiple choice question - by: Bielefeld

Hi,

This is possible (LS version = current) by using the nice
feature "Relevance equation" for the sub-questions
of your matrix with a little trick:

The depending item (here: your matrix) cannot be in
the same group with the question that restricts the item.

Reason: The is no dynamic reload of the sub-questions
depending on previous selection actions on the same page,
so there has to be one "Next"-button-click between these two.
Plus: You must use the default of one group per "page"
which enables the "Next"-button between groups/pages.

Since there is no "Set conditions"-button in the top menu
when editing sub-questions, you will need to understand the
syntax of these conditions first, e.g. by defining conditions
for a dummy non-sub-question and copying them over to your
actual sub-question relevance equation fields...

Cheers,
Stefan
