ERROR: Symbol as array index

[bcarpenter]

I get this error when I try to track a package. Seems like the library is trying to use an Array as a Hash or something like that.

?> fedex = Shippinglogic::FedEx.new(key, password, account, meter)
=> #nil, :production_url=>"https://gateway.fedex.com:443/xml", :test_url=>"https://gatewaybeta.fedex.com:443/xml"}, @meter="">
>>  tracking_details = fedex.track(:tracking_number => "000....000")
