Why doesn't this if else statement work it keeps entering error?

I am trying to find the highest value for this set of variables but it keeps providing errors. I was wondering if the logic of the statements is wrong and how it can be fixed? h1=3 h3=4 h5=8

  if h1>=h3>=h5
    puts "example"
    elsif h1>=h5>=h3
     puts "w"
    elsif h3>=h1>=h5
     puts "e"
    elsif h3>=h5 >=h1
     puts "yeah"
    elsif h5>=h1>=h3
     puts "cool"
    elsif h5>=h3>=h1
     puts "bish"
  end
