Shape Layers: Undefined is not an object

I’ve used rd_GimmePropPath to get the Match Names for shape properties but I get an “undefined is not an object” error using the following:

app.project.item(1).layer("Shape").("ADBE Root Vectors Group")("ADBE Vector Shape - Ellipse")("ADBE Vector Ellipse Position”).setValue(-535,-311);

Any insight into accessing shape layer properties via scripting would be appreciated.
