I am using QTP 8.2 with .net add-ins. My action/test parameter windows input parameters has 2 extra columns name column1 and column2 in addtion to Name, Type, Defualt value and Description.
The output parameter tab also has the same columns and it also contains 8 rows and some junk values in column1 and column2.

When I try to declare input or output parameters under Name, type columns it is giving me error Parameter cannot be empty.

Can anybody help me?
