Dynamically Link Two Forms


I am Selasie. I am trying create a dynamic form between two forms.

  1. Registration form
  2. Follow up form

However, in deploying, the follow up form, i encounter this error:
ODK Validate Errors: >> XForm is invalid. See above for the errors. : Cycle detected in form’s relevant and calculation logic! The following nodes are likely involved in the loop: ${first_name} ${last_name} ${id_number} The following files failed validation: ${tmppgr9dg8u} Result: Invalid

Can someone please help me out?

Welcome to the community, @Selasie! You should be able to learn more about the dynamic data attachment through our support article here:

Thank you @Kal_Lam for your warm welcome.

I’ve gone through the documentation yet I am still having some errors.

Can I please share with you my parent and child file to see where I fall short?
