# ^^^^ we won't want to define our instance variables here, they should be within the 'get' block below:

get '/' do
 #this gives us access to @matches in our view (which you loop through correctly in the view)
 
 @matches = array

  erb :home
end 

post '/search' do 
 
 # great use of params!
 
  @search = params['search']
  
  # erb :search 
  # ^^^ should be the last thing we do 
  # (we don't want to display the view until the end of this method)
  
  # we want to check if the @search is equal to our home country. 
  # if it is, let's add the match to an array (since there could be more than one result)
  # In order to do this, we need to check the home team of each match
  
  # try something like this:
  
  # set up your results array:
  
  # @results = []
  
  # loop through all your matches to find the one that equals the user's search
  
  #array.each do |match|
  #  if @search == match['home_country']
  #    @results << match
  #  end
  #end
  
  #what you'll end up with is an array (@results) that contains matching search results
  
  # then this part is not necessary:
  
  if @search =  @home_country 
      "<%=@home_country%> Vs. <%=@away_country%>"
  elsif @search = @away_country 
  end
  
  #finish by displaying the view with @results
  
  erb :search
