So what you need to do is just un-qoute todo.count. So it should look like this.

println(todo.count)

this is because when you add quotation marks you are making a string that you are trying to print out. When you want to call a method why using the println() all you need to do is just type the name of the method. Hope this helps!!!

The "" around todo.count is making it a string...remove the quotes and you good.
