Hey there!
 
	Im developing some HDA´s for my Bachelor Project!
 
	My actual Problem is about the Action Button for a Prim Group Selection.
 
	Right now im running the standart Action Button script below:
 
	import soputils
 
	kwargs['geometrytype'] = (hou.geometryType.Primitives,) 
	kwargs['inputindex'] = 0 
	soputils.selectGroupParm(kwargs)
 
	But, of course it does refer to the Node above the Subnet.
 
	My question is:
 
	How can i refer to the Node above the Selction Node inside the Subnet ?
 
	Is it a Python Callback Script or is it something below the Action Button ?
 
	 
 
	Thank you very much
 
	Max
