I have a survey with multiple repeats and they are somewhat connected. Lets say one repeat is for general information about areas, and that every area you create gets a number (1, 2, 3, 4.... 100) which the user selects from a select_one list. Then there is another repeat for species and for every species you should select which area it was found in (1-100). I would like to make sure that when you select which area the species was found in you only get a list of the areas that are created so far (if there are 5 repeats for areas I only want the numbers 1-5 to be selectable instead of 1-100). Is this possible?
