I have a step in a task that uses Calculate Field to change the value of one field in one record of a table in a file geodatabase. After it calculates, I want to copy that value from the table and assign it to a variable to use in a future step. However, when I set up an action under "When exiting the step" to Copy attributes from Feature or record modified in this step, I get the error message: "Error: Cannot retrieve attribute. Unable to retrieve selection modifiedInStep." Can anyone help me fix this?
