Benchmarker Error

Why is the code not working and what am I missing here?

I want to add in the space between "elapsed" and the puts statement:

benchmarker = SimpleBenchMarker.new

but it does not recognize the variable at all.

I also tried adding above @benchmarker, attr_reader and a couple of other combinations and this isn"t working.

Idea?

simple_benchmarker.rb 
class SimpleBenchmarker
  def run(description, &block)
    start_time = Time.now
    block.call
    end_time = Time.now
    elapsed = end_time - start_time

    puts "\n#{description} results"
    puts "Elapsed time: #{elapsed} seconds"
  end
end

benchmarker = SimpleBenchMarker.new, there's typo here, it's SimpleBenchmarker, m in lowercase.

Sorry I tried it with lower case m and it is still not working.

((Bummer! The benchmarker variable was not found.))

Something is wrong with the form.

I did not use all lower case. I put "SimpleBenchmarker.new" I also copy/paste your answer there.

((Same error: Bummer! The benchmarker variable was not found.))

Why is it not finding the new variable? I am trying to define it by call the new method on SimpleBenchmarker. Is something wrong with the website? Maybe a bug if it can not recognize what I'm doing...

I also already passed other challenges after this one. Only this challenge is stopping me from getting the badge.

    puts "\n#{description} results"
    puts "Elapsed time: #{elapsed} seconds"
  end
end

benchmarker = SimpleBenchmarker.new
