Hello.
Thank you for always referring to the Kobo community forum.
I would like to ask you all about the relationship between the introduction of the new household id and data input in Dynamic Data Attachments.
I thought about displaying the demographic data collected in the first survey in the second questionnaire using the household id as a key.
In order to quote the data, I entered a code starting with instance() into the calculation of XLSForm.
This allowed me to enter the Household id collected in the first survey into the second questionnaire and quote data such as age, gender, religion, etc. Everything was going well up to this point.
However, when I entered a new household id in the second survey form that was not in the first one, the survey form displayed the following message and was forced to close.
“Error occred: Failure trying to update values. this is generally due to incorrect usage of calculations in the form design. if you keep having this problem, report it to the person who asked you to collect the data.”
Is there an alternative to entering a new Household id and continuing the investigation?
I would appreciate your response.
