You have a few issues here:

  • you wrote "lenght" instead of "length"
  • you don't need a property in the comparisons
  • you do need the property for the "int" method
  • calling "int" inside the "int" method creates an infinite loop
  • some comparison operators don't match the names of the methods

I'm curious. In the Treehouse code challenge, I called "int" inside the "int" method ( int ), and I didn't experience an infinite loop. Does anyone else get the inf loop?
