Hi, I have created a repeating a group which contains products and their geographic address. I want to create a drop down box which allows the user to rank the repeating group by items which are closest to them. From the image attached, this is the closest I have managed to get, but I cannot seem to find a way to attach a drop down box to trigger the ranking.
Eventually I want to do this with price etc so it would be great to know how to do this please. Any help is greatly appreciated!
