Importing Instance Table Data into Activity Diagram

[mgs11210@gmail.com]

I am trying to create an activity diagram that imports data values from an instance table, runs through those values and makes decisions based on those values to assign values to other variables (this uses decision nodes and value specifications to assign the new values). I have been successful in creating the activity diagram that does these logical operations, but it currently requires that the user inputs data values before each run. Not too sure how to import data that can be ran through automatically. Would love any assistance that can be given! I currently have activity parameter nodes in the diagram but those are not importing values from the instance table.
