Print out the number of items in the todo array using println.

Why is this still not accepting ? Line 2 shows printIn(todo.count) and I'm getting the error message saying I need to call 'count'. I've read other forums with the same problem and it worked for them. What am I doing wrong?

arrays.swift
var todo = ["Learn Swift","Build App","Deploy App"];
printIn (todo.count)

Sorry for posting this off-topic, but I'm helping Treehouse investigate a potential issue with their webserver. Please follow this link and leave a comment saying if you have experienced this webserver issue or not.

Thank you.

You've written printin when the function you want is written println. The i and l look the same in different fonts, especially when the I is capitalized, so watch out for that. Think of the function saying "print line" makes it easier to remember!
