Load Selected Families from Directory

I’m attempting to create a graph that will look in a directory for families and then pop up a window so the user can select the families to ignore and will only bring into Revit the families that the user wants.
This graph is close in that it will list the families, but after I choose the ones to ignore, nothing happens. No families are brought into Revit. Can anyone please tell me what I’m doing wrong? Thanks!

what is the output from the List.FilterBySelection node?

Hi Jacob-
Here is an image of the outputs.
