In this case, the rule needs to go on the text box - add a formatting rule to hide it unless the value of the dropdown is what you want. I've attached a sample - save the file locally, right click and select Design. From there, you can see the rule on the textbox & you can preview the form to see how it behaves.https://www.infopathdev.com:443/forums/thread/109154.aspxFri, 13 Jan 2017 20:27:51 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:109154Jose Leandro0https://www.infopathdev.com:443/forums/thread/109154.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=109154How do I make a text box appear when a certain dropdown selection is made? When I try to create a rule I don't know how to call on that particular text box in the rule. Your help is much appreciated.
