Extending a Native Type Code Challenge
Every time I check my work it says, "Bummer: Make sure you're adding an add method that takes an Int and returns an Int?" I am pretty sure my syntax is correct, and I don't know what I am doing wrong.

There are some small mistakes. First, your return has to be optionall so its Int? not just Int. Also ”self” is spelled with lower case letters. Hope this helps
I tried that, but it's still saying the same thing. I've even tried other people's answers that they said worked, but it still does this.
Ok, now it worked. Thanks!
