Hi Raymond,

You need to close the curly brace of the if statement and add some whitespace around your conditions. Put some spaces to separate the operators. It works fine, then.

Hi Raymond,

This will work - I just closed the brace and added spaces between the operators:

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

You can also lose the parentheses around the conditions:

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

Steve.
