Relevence for Skip

Hello,
I am new to ODK. I have been trying to use the relevance feature in the
advance tab.
Attached is a sample.
I want the Name question to be asked only if the person is above 18 years
of age.
How can it be achived.
The present expression I have put in the relevance tab does not seem to
please aggregate.
I always get an error while uploading the form to aggregate.

Would appreciate any help.

Thank you.

Not sure how you are generating the form.

The XML file syntax is different from the XLS syntax.

In the XML file, the proper bind would be:

In the XLS file, you would specify ${age} = "y"

When we process the XLS file, we look for ${...} and expand it
appropriately. The substitutions required for values to exapnd into text
labels and for formulas are different, so having the one unified ${...}
syntax in XLS simplifies the form design process.

Oops -- looks like there is an extra close paren in the bind that I missed.

  <bind nodeset="/data/name" type="string" relevant="/data/age =

"y"" jr:constraintMsg="jr:itext('/data/name:constraintMsg')"/>

Ram,

Looks like you are using ODK Build. Try using the full path when you
use the ${} syntax. ${/data/age} should work. If it doesn't then there
is a bug.


has examples.
