Scott :
However whenever I pass which_country into the following line of code record_select :per_page => 10, :search_on => 'full_name', :order_by => "field(country, #{which_country})"
I get a undefined local variable or method `which_country' for UsersController:Class error.
Has anyone any suggestions on what is going on and why it can access the value within a method but not within the above code
Maybe because you should have a instance method called which_country and also a class method called which_country.
