Good day Modurator. How can one define an instance_name, when the question group is a roster.[Question with repeat]?The one illustrated from Odk documentation support only works with a question with no repeat.

I dont want to manually enter the instance_name.

Please, i need a solution to this.
Image above is the one shared by the community, for instance_name when the question type doesnt repeat.

Thank you

Maybe you could do it (by using a variable that extracts the value form a roster) as outlined in the post discussed previously:

Thank you. Buy how do I place the variables on the settings tab of the xls sheet ?

Non roster questions are quite easy.just concatenate the variables…but in this case of a repeat questions,is some how daisy?

I intend to give a unique name to every name_instance…so that each entry can be identified…

Thank you
