Element.SetName Help


I have been using the element set name node with success for awhile, but today it keeps on returning null. The image below is just an example, i have a script that is pretty extensive that has worked for awhile but now its getting this null problem like the example. Is there something i am missing. For some reason it says GETS the name of the given revit element when i hover over the element.setname node.

Never mind, I figured it out. One of my addins (Project sweeper) was breaking it.
