Using ArcPy to fit polygons inside another one

Question

I have been trying to solve a bin packing problem using a Python script I found, but when I try to use it I get an error that I don't know how to solve.

The code that I'm trying to use is taken from here: Fitting known size polygons into irregular polygons using ArcGIS Desktop?

What I am doing is creating 2 shapefiles with polygonal entities and I create a geoprocessing toolbox, I add the python script and I open it. When I open the tool I enter the layers of the shapefiles as parameters, and I execute it.

Possibly this is a simple error, but the truth is that I don't know how to solve this problem.
