Ok you are going to have to explain that to me again, how catName is greater than dogName based on how/when it was declared? Oh, did you mean alphabetically? Ozma \> Mango would be true in that case. ---

That’s exactly right - the less than and greater than operators, when used with strings, compare them alphabetically. One string being greater than another string means it comes “later in the dictionary”, alphabetically speaking. ---

Hey @george30: we’re moving to GitHub to store our video materials now. You can browse through the different folders in the repository to find the challenge solution, or you can download all of the materials in one fell swoop with the “Code” button: ![image](https://files.chunter.kodeco.com/original/3X/0/7/076a30a31755ff45b9c846c8be28c926fe5adc4d.png) Hope that helps - let me know if you have any more questions! ---
