How to make this code correct?

Question

I have no idea how to answer this question: I don't remember a video on random numbers and get calls.
```fish.rb
require "sinatra"
get "/fish/:number" do
  "I see #{params[:number]} fish!"
end
get "/fish/random" do
  "I see #{rand(20)} fish!"
end
```

I see you learned some Ruby, routing-- let's build on that.
Three things you need to make this work--
1 - you need to set up a binding to an ip address.  This is required to get Sinatra to listen on an ip address other than localhost (127.0.0.1).  You don't need this to develop on your local computer, but you do need this for TreeHouse workspaces.
set :bind '0.0.0.0'
2- you often need to have Sinatra listen to a port other than its default port of 4567.  On TeamTreehouse, 8000 is one of those ports that you can expose to the outside world.  (note: you can also omit this since TeamTreehouse also supports visibility on 4567)
set :port 8000
3 - Finally, you need to look at the URL routing order.  In this case, you need to go from most specific to least specific.  You have to have the /fish/random route come first, since that is a very specific URL.  And after that you can have the fish route with the parameter.  See below.
```ruby
require 'sinatra'
set :bind, '0.0.0.0'
set :port 8000
get "/fish/random" do
    "I see #{rand(20)} fish!"
end 
get "/fish/:number" do
    "I see #{params[:number]} fish!"
end
```
