**panic: runtime error: index out of range [1] with length 0

goroutine 1 [running]:
main.main()
        C:/Users/Afra/Desktop/main.go:39 +0x868
exit status 2**

How fix that and why it happend ?

Without seeing the whole code it's a bit hard to say but here:

• referrerID, _ := strconv.Atoi(match[1])
• and on error **panic: runtime error: index out of range [1] with length 0
  => you are trying to access slice index 1 which doesn't exist. Actually length of that slice is 0.
