Dear community, i designed a survey containing one main frame and two loops to provide multiple selections of location by a needle. The produced data should be analyzed directly online by queries. My problem is that its not possible to combine the data from the different loops or the main frame (different data layer). I tried to make join by using the global and the parent ID, respectively. This didnt work neither. Is there any common difficulty in doing such a join or is there another way to solve the problem, maybe by an expression in the initial excel sheet of the survey so that all loop inputs are automatically copied to the main frame? Any other suggestions or alterations of survey123 itself? Thanks for helping, Till.
