What's wrong with this code please?

This code is working on Xcode, why not at tester

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

for n in 1...100 {
    // Enter your code below
    var value2 = n % 2
    var value7 = n % 7

    if value2 == 0 && value7 == 0 {
        results.append(n)
        }
    // End code 
}

your spacing is incorrect.

change value2! = 0 to value2 != 0

the below solution works

var results: [Int] = []

for n in 1...100 {
    // Enter your code below
    var value2 = n % 2
    var value7 = n % 7

    if value2 != 0 && value7 == 0 {
        results.append(n)
        }
    // End code 
}

you're checking for even and not odd.

try this value2 != 0 instead

Thanks, Ethan. We are trying to find how many numbers from 1 to 100 are odds and multiple of 7.

value2! = 0 won't work it out.

Thanks, again
