我正在学习围棋。当我试图在切片中添加一个名字时，它并不包含以前的名字。有人能告诉我出了什么问题吗？（以下是代码）

package main

import "fmt"

func main() {

    eventName := "Go Event"
    const totalTicket uint = 50
    var remainingTicket uint = 50
    fmt.Printf("Welcome to our %v booking app!\n", eventName)
    fmt.Print("Get your tickets now!\n")

    for {
        var bookings []string

        var userName string
        var userTickets uint

        fmt.Println("Enter your name")
        fmt.Scan(&userName)
        

        fmt.Println("Enter the amount of tickets you want to purchase")
        fmt.Scan(&userTickets)

        bookings = append(bookings, userName)
        remainingTicket = remainingTicket - userTickets
        fmt.Printf("All the bookings: %v\n", bookings)
        fmt.Printf("User %v booked %v tickets\n", userName, userTickets)
        fmt.Printf("Remaining Tickets: %v\n", remainingTicket)
    }
}
