I think I can get your Module to work by removing the arguements that it needs to be passed to it. In actual fact you are trying to use it incorrectly as it is designed to Rename 1 Field and you want to rename 52 of them, although how you know what order the Imported ones are compared to the names in your table I am not quite sure.
I can certainly loop through the names in the Table but how can I match them up to the names in the Imported Table?
