Not sure why I keep getting expecting end of input syntax error

puts 'Lets talk to grandma'
talk = gets.chomp 
x = 100

while x > 0  
  if talk == talk.upcase    
    puts 'NO NOT SINCE' + ' ' + rand(1900).to_s + '!'   
  else      
    puts 'HUH'  
  end
 ​
  if​ talk == ​'BYE' 
    ​break​
  end   
end
