What I want to do is simple. Based on the choice made on a dropdown field (e.g., country: 1. USA or 2.Canada) I would like to show the relevant address field (zip code for USA or postal code for Canada) and hide the irrelevant one. I researched old posts and I think the following post is the closest match to my need: http://fabrikar.com/forums/index.ph...eld-elements-based-on-parent-selection.43461/ If I understand correctly, I will have to go to the Country field, navigate to options, and then add JS code to do that. The difference from the post above, however, is that I do not need to create a separate group within the form. I also do not know much JS, unfortunately. So if anybody can help with adapting the solution above to my simpler situation and with the JS code, I will be grateful. Thanks in advance.
