I have a web service that returns values val01, val02, val03.  In the workflow, the webservice works and it returns the 3 values.  If I want val01, val02, val03  to be displayed in my workflow,  I need assign it to my workflow variable land, building, total respectively.  How do I accomplish this inside my workflow? 

I'm having issues integrating my web service with docuware. I published my both my rest and soap  web service using IIS. I tested it using Postman with no errors. However, when I try to start a new web service in docuware. I get an error which reads below.
         Validation failed with error: An error occured while sending the request.

             Thanks!
