Returning data from sub-form

I have an ODK2.0 form which contains a linked_table to a form (let’s call it the “child” form). In the child form, the user will enter a single integer called “numberOfCans” and then finalize that child form instance. How can I return this integer value back to the parent form for use for validation in the parent form? Would it be something like data(’<some_unique_form_id>.numberOfCans’)?

Hi @roundcubefour ! As you are new to the community, when you get a chance, please introduce yourself here.

I’d also encourage you to add a real picture as your avatar because it helps build community!

This is doable! You are going to need to use queries and async_assign to feed the data back up to the parent form. See here: for some details and examples of async_assign and let us know any follow-up questions after that.

Thanks @elmps2018 i’ll follow it shareit app
