Dear ODK community,
I've got a repeat group of household members. For the selection purposes,
I'm generating a random number for each member and trying to get the name
of the household member which has highest random number in the nodeset.
Is it possible to get a position of the highest random number?
Best,
David
Hi David,
I think it's possible but probably not easy. You'll have to use some
combination of indexed-repeat() and max(). Other functions you can use
are at https://opendatakit.org/help/form-design/binding.
Build things incrementally and send out a very short example form to
the list if you get stuck.

And you will want to wrap your use of random() with once(). Otherwise,
each time you edit the form, new random values will be generated.
