Revit to excel to revit


I am working on a workflow from revit to excel and back.

This is based on the archsmarter tutorial. I’m able to get the data out easily. My issue is as the final step where I am greeted with the following error

Any assistance is greatly appreciated

The wire that connects to the element input port of Element.SetParameterByName should be from All Elements Of Category node and not the Category node (as it seems to be in your screenshot)
