How do I send my 'If' statement results to the 'results' variable?

I believe I have some if not most of the challenge close to completion but I can't seem to work out how to send the results from each loop back to the variable called results. Please help!

Hi again

So, I used the append method instead:

var results: [Int] = []

for n in 1...100 {
    // Enter your code below 
    if n % 2 == 1 && n % 7 == 0 { 
        results.append(n) 
    }
    // End code
}

Also, you should always write if n then ... (in the code above you are starting with 2%n) If that makes any sense :-)

Use the += operator to add the number to the array if all conditions are true: results += n

I tried but it keeps coming up with an error asying "Binary operator += cannot be applied to operands of type [Int] and Int"

Can you please copy and paste your code in? Then I can see what's missing :-)

Sorry heres the code I have put in

var results: [Int] = []

for n in 1...100 {

    if (2%n != 1) && (7/n != 0) {
  results += n
}

}
