Rules run when a field changes. So if the rule is only on field A, it only runs with field A changes. Make sense?</p>https://www.infopathdev.com:443/forums/thread/102970.aspxThu, 25 Jun 2015 18:55:30 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:102970autodafey0https://www.infopathdev.com:443/forums/thread/102970.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=102970I have a rule running to capture data from two fields and concatenate them into a third. Fields A and B are both text, but B is a drop down. It works fine when the user enters the data the first time and creates the third field with no problem. However, it&#39;s conceivable that the user may enter this wrong and not notice it until later. When you go back and change field B, the third field is not recalculated. I&#39;m sure there&#39;s a simple fix for this, but I can&#39;t seem to figure it out.
