I have a form with a select date variable, using the yyyy format. Based on the year that they select, I would like to create a new (preferably hidden) variable that generates this selection in the format of a two year range (e.g. yyyy-yyyy) with the first year in the range being the one selected in the previous question. I could manipulate the data set after exporting using a different software, but it would easier to add a calculate question within the form so that the new variable exists prior to exporting. Is this possible?
Hi @hakan_cetinkaya. Thanks for the suggestion, but I don’t really understand the process after reading about the functions. Is it possible to do this within form builder or would I need to make my own formula in the calculation column of the xls form? Would the formula be nested, as in date(calculate(decimal-date-time(question_1)+365))?
