The variable z does not contain an index but the object you need. Try

direction.each do |z|
n = z.attribute["id"]
result << n
end

This should also work:

result = direction.map{|z| z.attribute["id"]}

Thanks for the reply; however, both of these produce a new error is
being produced:

Error: #<ArgumentError: C:/Program Files (x86)/Google/Google SketchUp
