I want to know if is there a way to use a relevance bind that make a
question relevant if the prior question is not a value or is different
on a text question.
i have a question that ask for at least three text answers so i make a
group of text questions where the first three are required. But is
there a chance that the interviewed person didnt know any answer. So i
want to skip the other text fields if the interviewer puts "99" or
"didnt know".
My logic is to make the other tho questions relevant if the prior
answer is different to "didnt know"
To make a question relevance depend on a prior question's relevance
you will need to use a variable for the prior question. The variable
is based on the question name. For example, if I have a question named
"amount" then the variable I use for it will be ${amount}. You can use
these variables in any javarosa supported XPath formula (see: https://bitbucket.org/javarosa/javarosa/wiki/xform-jr-compat). For
example, if "amount" is a select_one type question and you want to
skip a question if someone selected "didntknow" (select values can't
have spaces, although their labels can), then you would put:
not(selected(${amount}, 'didntknow'))
in it's "relevant" column.
I hope this helps,
