XPath error in an application

Hi everyone,

I have a little issue at CommcareHQ. When I try to test the app that I have developed, it shows the next error message:

Do you know how I can resolve it?

Best regards,

is yes_no a lookup table you're using? That error means that you have a reference which points to more than one item. You'll need to add a filter expression to that reference so it resolves to only one item. Can you attach a screenshot of that question in the form builder?

Thank you so much for your response.

Yes, yes_no is a lookup table, but it only are referencing one item (there is only one "yes" and only one "no").

field: table_name field: name label: lang 1 field: label 1
yes_no yes en Yes
yes_no no en No

Best regards,

What does the configuration for "Lookup Table Data" look like? It should be something like this

Is it possible there's anything else referencing that lookup table, maybe a hidden value that calculates the label corresponding to the user's selection, for example?

Yes, thank you @Ethan_Soergel for your response.

I found this post from Commcare and following all the steps I can resolve it.
