What is the problem?
I am conducting a survey on Samsung Galaxy Tablets A(2016). I have repeating question regarding the number of household members. I noticed that it is difficult to update the number of household members once the survey gets to questions about that household member. For example, if the surveyor reports that there are 2 household members they will have questions about household member number 1 followed by questions about household member number 2. However, if there are not actually 2 household members and actually just one, even if the surveyor goes back and enters 1 household member; they will be asked about the second household member.
