       ###Refresh selections
       groupSelection.append(nuke.selectedNode())
       newGroup = nuke.selectedNode()

       ###Paste Attributes
       newGroup.knob('xpos').setValue(nodeXPosition)

       ###Connect Inputs

       newGroup.knob('name').setValue(nodeName)

       newGroup.knob('selected').setValue(False)

   ###Cleanup (remove gizmos, leave groups)
   for y in gizmoSelection:
       y.knob('selected').setValue(True)
   nukescripts.node_delete(popupOnError=False)
   for z in groupSelection:
       z.knob('selected').setValue(True)
   for w in noGizmoSelection:
       w.knob('selected').setValue(True)
