I ask a question to answer multiple options. If I select 3 options out of 5 then need to ask another question for each selected option. After that, I would like to calculate the sum of selected options.
Example:
I ask a question about what type of product was purchased last month: The answer may be Nut, Oil, Onion, Garlic, Rice. The response was: Oil, Onion, and Rice.
After this question found to ask the quantity of every selected product individually (here set a skip logic).
Thanks @Kal_Lam for response. I think that I am not express my question clearly. I would like to say after choosing the multiple options I requested to enter the number (as per skip logic those you shared) then I would like to calculate the sum of those numbers. I gave a formula in the calculation field and worked in Enketo well but not working in-app.
