title: TypeError: 'int' object is not subscriptable
body: <p>I'm trying to create a simple program that tells you your lucky number according to numerology. I keep on getting this error:</p>
  
  <pre><code>File "number.py", line 12, in &lt;module&gt;
      sumln = (int(sumall[0])+int(sumall[1]))
  TypeError: 'int' object is not subscriptable
  </code></pre>
  
  <p>My script is:</p>
  
  <pre><code>birthday = raw_input("When is your birthday(mm/dd/yyyy)? ")
  summ = (int(birthday[0])+int(birthday[1]))
  sumd = (int(birthday[3])+int(birthday[4]))
  sumy= (int(birthday[6])+int(birthday[7])+int(birthday[8])+int(birthday[9]))
  sumall = summ + sumd + sumy
  print "The sum of your numbers is", sumall
  sumln = (int(sumall[0])+int(sumall[1]))
  print "Your lucky number is", sumln`   
  </code></pre>
