Could you please let us know what is the logic behind the Custom Logic in Mandatory Response and the use of Custom Logic in forms.

Regards,
Keerthi.

Hi @adepuk,

It’s not always that you wish to see your variables mandatory (where the variable should be filled, else the filled-up form would not get submitted to the KoBoToolbox server) or optional (where the variable could be left blank and the filled-up form could still be submitted to the KoBoToolbox server). You might sometimes wish to make it mandatory for certain criteria.

It is a form of a mandatory response if and only if it meets a certain criteria else it would act as an optional response. You could define the required criteria in the text space of the Custom logic.

For further understanding please have a look at the images shared below:

In the survey tab of your xlsform:

In the choices tab of your xlsform:

Hello
I do not understand well custom logic with that example. I still do not see the difference between optional and custom logic, do you have another example?
Thank you

Hi @alinephilibert,

Would you mind trying out the workaround (shared with the post). Try entering a dummy response from the same and you should be able to have a picture of what a mandatory response is and what a custom logic is.

Also please feel free to have a look with one of our other discussion related to custom logic (it should be helpful for you):

Have a great day!
