Python, Get normal from current point and apply to instance

[hindukush 1]

Hi everybody i'm stuck orienting light copies to the point onto i scatter.

Can anybody tell me what is wrong with this opiece of code?

 

for pt in scatterGeo.points():         

            euler = pt.findPointAttrib(“N”)
            dir = hou.Vector3((0,1,0)) * hou.hmath.buildRotate(euler)
            instances.parm('rx').setAttributeValue('N ',dir[0] )

 

 

I think there are some basic python stuff error in there:-)
