Question Why does intersection/pick return the geometry object?

I have hopefully an easy question.

I created a menu in 3ds max, where I cut out a series of buttons and want to perform simple intersection tests to make various things happen.
Right now, I'm just trying to properly detect the right object using:

Code:
line = viz.screentoworld( viz.mouse.getPosition() )
intersection = viz.intersect( line[0:3], line[3:] )
print 'intersection:', intersection.object
print 'intersection:', intersection.name
In the inspector, the geometry node takes on the name of the material as seen in the attachment. Therefore, all the objects have the same geometry node name.

I wanted the intersection test to detect each object independently of one another, but all I get is the following on everything I click on:

intersection: __main__.VRC_Auto(1)
intersection: VRC_Auto_M

Now, in the case of a different object with no materials attached, I get the geode returned to me instead. And I am able to easily delineate between the objects by the name and when I perform an intersection I can make all the special events ( such as activate animations happen) just fine. (see the second image).

Thank you,
George

The intersection test returns the lowest level sub-node in the scene hierarchy. To determine the name of the node above the geometry node set computePath to True when you call the viz.intersect command. The name_path attribute of the returned viz.Intersect object contains a list of sub-node names representing the full path to the intersected object within the scene hierarchy.
