Second Scanf getting skipped?

gistfile1.go

func getConnectionInfo() string {
	// Prompt the user for connection string info
	var servername, username, password string

	fmt.Print("Enter Server Name:")
	fmt.Scanf("%s", &servername)

	fmt.Print("Enter User Name:")
	fmt.Scanf("%s", &username)

	fmt.Print("Enter Password:")
	fmt.Scanf("%s", &password)

	connstr := "Server=" + servername + ";user id=" + username + ";password="  + password
	return connstr
}
