You'll need to do a little more work here to send the form's data to the POST request. In this case, you'll need to use something like params["string"].reverse. In Sinatra, Params returns a hash. By giving your text input a name, you've created a key in that hash with the same name. The value of that key is the value that was entered in the form. So to access that value you'll look at the "string" key in the params hash using params["string"]. From there, you can reverse the string using the Ruby method .reverse.
