Cleaning it up.

  1. It looks like you were missing a '}'
  2. I wrapped the expressions between your && operator
  3. changed the '& *' to '%'
var results: [Int] = []

for n in 1...100 {
  if  (n%2 == 1) && (n%7 == 0) {
  results.append(n)
    }
}

After the && n there's a & that doesn't belong there. Try deleting that.

Bummer! Make sure you are performing logical checks in the condition of the if statement

Oops I think I see the problem. You have if n * 7 == 0 it needs to be if n %7 ==0 and also delete the & after n. I think this will get it to work.
