Hi,
I created Test and then I created Data Set.
In Dataset window I created 3 parameters. Two of them is "text" and one of them is "list".
One of the text parameter has only text values . Second text parameter has assigned only numbers values.
In test steps I refer to parameters like ${parameter_name}. In test execution I have 3 iterations. And when I expand every Iteration section I get all parameters values in test steps apart from parameter that contains numbers. This parameter doesn't show value but "${parameter_name}".
