What steps will reproduce the problem? 1. The web_service.rb file includes the method postal_code_search which takes three arguments. Immediately following this definition is another definition of postal_code_search which takes one argument. Since we are dealing with Ruby here, the first method gets overwritten. 2. Even if this did work, there is a typo in the body of the method which renders it useless. postal_code_sc.coutry_code = country_code should be postal_code_sc.country_code = country_code

What version of the product are you using? On what operating system? geonames 0.2.2
