You want to set up this filter so that that the Release Number in the dropdown = the Release Number in the external list.</p><p>Hope this helps!</p>https://www.infopathdev.com:443/forums/thread/88475.aspxThu, 28 Mar 2013 19:11:55 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:88475drmandel0https://www.infopathdev.com:443/forums/thread/88475.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=88475<p>I am trying to set up the following:</p> <p>1. I have a drop down field that lets the user select a &quot;Release Number&quot; from a drop down list that is using a lookup to an external list.</p> <p>2. I want to create a rule that will result in displaying related information that is also in the same lookup list as the Release Number. So for example when the user selects the Release Number, I want to display the related Release Date.</p> <p>3. Currently what is NOT working is I have a rule that has a condition = When Release Number is not blank and I have a rule type of Action = set a field&#39;s value... but I cannot figure out what formula will result in displaying the Release Date related to the Release Number.</p>
