https://community.esri.com/t5/arcgis-field-maps-questions/trying-to-use-a-calculated-expression-to-display/m-p/1336760#M7178 <P>I am trying to create a calculated expression that will return a numeric value from one field in the feature class with a description from a coded value domain in another field in the same feature class. The goal is to concatenate the two fields to give a unit number and description/characterization that can be used for map labels. I think that I need to use the "DomainName" function, but I have not been able to make it work. The numeric field is called "Unit_Number" and the field with the coded value domain is called "Stream_Habitat". I am able to return the numeric value along with the coded value, but I want to return the description, not the coded value. I think if I was able to see examples of the DomainName function, I could figure it out, but the help post on ESRI has syntax only.</P><P>Here is my functioning code block that returns numeric value and coded value:</P><DIV><DIV><SPAN>Concatenate</SPAN><SPAN>([</SPAN><SPAN>text</SPAN><SPAN>(</SPAN><SPAN>$feature</SPAN><SPAN>.</SPAN><SPAN>Unit_Number</SPAN><SPAN>), </SPAN><SPAN>$feature</SPAN><SPAN>.</SPAN><SPAN>Stream_Habitat</SPAN><SPAN>], </SPAN><SPAN>' '</SPAN><SPAN>)</SPAN></DIV></DIV> Tue, 10 Oct 2023 21:28:50 GMT tvelez 2023-10-10T21:28:50Z https://community.esri.com/t5/arcgis-field-maps-questions/trying-to-use-a-calculated-expression-to-display/m-p/1336760#M7178 <P>I am trying to create a calculated expression that will return a numeric value from one field in the feature class with a description from a coded value domain in another field in the same feature class.
