Generator not drawing along spline

[QuickSilver]

I based my scene on the 21_CGExtrusion example included with the package. I'm trying to extrude a closed 2D/Circle input spline along a spline path. Everything is connected correctly in the Generator and the circle spline is on the XY plane but it doesn't extrude along the path it just seems to spin right around where the circle is placed (0, 0) relative to the parent plane everything is attached to. How do I get the mesh to generate along the spline attached as the input spline path?
