Thank you so much KRIS NIKOLAISEN , it finally worked. You were so quick to answer and made me understand clearly. Thanks again.

package blackjack



func PlayHand(score int) string {
  // YOUR CODE HERE
  if score < 17 {
    return "hit me"
   } else if score > 21 {
   return "bust"
    } else {
    return "stand"
     }
}

You won't be printing anything so you don't need import "fmt". Then if you just replace each fmt.Println with return and eliminate the last return you already have you should be good. Also note: "Stand" should start with a lowercase "s".
