Hi Kobo team!

I am trying to link two projects in Kobo, one parent and one child. When I try to link them, I get this error. Can someone help me, please?

Best,

CUNGA.

Hi @AbelCunga

Do you see the error message after selecting the questions you want to import? I have seen that error when there is a duplicated question name, could you check that in your child form?

A short video or screenshots with the steps you are taking might help us to guide you better!

@pahoy& @Kal_Lam thank you for your help! I have sent the screenshots of my parent and child projects. And note that, there is a repeat group in child project.

Hi @AbelCunga, Thanks for sharing these. To better understand the issue, could you please share a screenshot from KoboToolbox itself showing the error, along with the steps you take before it appears?

Instead of screenshots of the XLSForm, it would be much easier for the community to help if you could share the XLSForm file directly (if you’re comfortable doing so).

Also, have you had a chance to check whether there are any duplicate question names in your child form? That’s one of the common causes of this error.
