What am I missing here?

Did I miss something or did I misunderstand what it is asking me to do?

var results: [Int] = []

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

stephanie, if you check the error message in Preview you will see this:

swift_lint.swift:9:31: error: '!=' is not a prefix unary operator
    if (n % 7 == 0) && (n % 2 !=0) 

what it's trying to say is that it has a problem with !=0. What it wants is != 0. If there isn't a space before the second operand it thinks you are asking it to use ! as a unary operator (sort of like the - in -x). So if you just change it to the following you will be fine:

if (n % 7 == 0) && (n % 2 != 0)
