I'm glad you found a solution for your scenario.
If a test uses the Test Studio data driving feature, then the test will repeat until it has iterated through each row of the data source. You can filter between specific rows
to specify the particular rows that the test will iterate through, but not make references in one iteration of the test to multiple rows of your data source -- unless you resort to code.
Specifically, you can access the content of a particular cell in your data source using the following C# code, which sets value to the content of the "Amount" column for row 2:
object value = ExecutionContext.ActiveDataRows["Amount"];
