[Closed] How can use a function name as object name?

I would like to use that function name (popo) as the object name.
But It was “undefined”
How do I modify the function below?

 fn CreateConObject ConOBJ OBJRadius = 
(
	 local conObject = ConOBJ
	 conObject = Circle radius:OBJRadius pos:[0,0,0]
	 conObject.name = ConOBJ as string
	 convertToSplineShape conObject
	 conObject_copy = copy conObject
	 rotate ConObject_copy (angleaxis 90 [0,1,0]) 
	 addAndWeld conObject ConObject_copy 100
	 conObject.render_displayRenderMesh = true
	 conObject.render_thickness = 1.5
)
CreateConObject popo 10
