I get this error:

wiki.rb:7:in `read': can't convert File into String (TypeError)
        from wiki.rb:7:in `substitute'
        from wiki.rb:12


with code:

require 'fileutils'

        f1 = File.open("original.txt")
        f2 = File.open("canviada.txt")

def substitute(source,dest,find,replace)
  data = File.read(source)
  result = data.gsub(/#{find}/,replace)
  File.open(dest,"w") { |f| f.write(result) } if data != result
end

substitute(f1,f2,"ol","ur")


What happens?
Thanks,
Xan.
