iOS Swift 2.0 Collections and Control Flow Control Flow With Conditional Statements Working with Logical Operators

What am i doing wrong?

This is what it is telling me:

Double check your logical conditions to ensure that the value being appended is both odd and a multiple of 7.

Can someone please tell me what to fix, I'm pretty sure it has something to do with my if statement parameters.

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


for n in 1...100 {

    var multiplesOfSeven = n * 7
    var oddNumbers = n % 3

    if multiplesOfSeven < 100 && oddNumbers < 100 {
        results.append(multiplesOfSeven)
        results.append(oddNumbers)
    }
}

var results: [Int] = []
for n in 1...100 {
// if n is an odd number and n also a multiple of 7 then append n to the array  
    if n % 2 != 0 && n % 7 == 0 {
        results.append(n)
    }
}
/*
    try printing your result and you'll see that you only appending the result of 
        (n%3) and (n * 7)  that are less than 100 
*/
for a in results {
    println(a)
}

What you are doing is appending numbers that are less than 100.

var results: [Int] = []

for n in 1...100 {
    // Enter your code below
    if n % 2 != 0 && n % 7 == 0 {  // We are checking for odd and multiples of 7 
     results.append(n)
    }
    // End code 
}
