You've gathered the wrong column(s) See example below
So we do:
Clear

blib()

Function blib

	loOb =  Createobject('blablub')
	loOb.bla()
Endfunc &&blib

Define Class blablub   As Custom

	Function bla
		Return This.blub()
	Endfunc &&bla

	Function blub
		lnlevel = Astackinfo(lastack)
		?lastack(lnlevel,3)
		?lastack(lnlevel-1,3)
		?lastack(lnlevel-2,3)
	Endfunc &&blub
Enddefine &&blablub
