Everything looks right, but I can not get a correct answer from this challenge. Please help.

What am I doing wrong and can you please explain?

operators.swift 
var results: [Int] = []

for n is 1...100 {
    if (n % 2 != 0) && (n % 7 == 0) {
    results.append(n)
    }
}

Hey Dustin,

Your code is correct; however, it looks like you altered a key word in the preloaded code, and that is what is throwing the error.

You changed in to is in the opening for loop. It should read for n in 1...100. Fix that up and you're good to go.

Keep Coding! :dizzy:

You just have a typo in there, "for n is 1...100" should read "for n in 1...100", the rest of your code is exactly right.

Maybe this will work?

I'm not sure.

var results: [Int] = []

for n is 1...100 {
    if (!n) && (n % 7 == 0) {
        results.append(n)
    }
}

Nope, that won't work. Spelling error in for loop and logic is incorrect in if statement.
