Hi Frank,

Try...

colorHash[@localAddress] = self

About the...

homeHash[@localHomeAddressString].push(self)

1) Hash doesn't have any 'push' method (this is for Array).
2) homeHash[@localHomeAddressString] is probably returning 'nil'
because this key doesn't have any value associated with it. After
that, ruby tries to send 'push' method to this returned object.
