Can someone tell me how to fix this runtime error?
runtime error: bad client
proc name: ChooseCharacter (/mob/other/Choose/proc/ChooseCharacter)
source file: Login.dm,93
usr: Kanak (/mob/other/Choose)
src: Kanak (/mob/other/Choose)
call stack:
Kanak (/mob/other/Choose): ChooseCharacter()
Kanak (/mob/other/Choose): ChooseCharacter(Kanak (/mob/other/Choose))
Load an old player (11,145,2) (/turf/C_Creation/Load_Character): Click(Load an old player (11,145,2) (/turf/C_Creation/Load_Character))

Heres the CC proc:
mob
proc
ChooseCharacter()
var/list/characters = src.CharacterList()
var/newCharacterChoice = "New Character"
var/DeleteCharacterChoice = "Delete Character"
var/list/menu = new()
menu += characters
menu += newCharacterChoice
menu += DeleteCharacterChoice

var/result = input(src,"Character Creation", "Dragonball Zen") in menu

if (result == newCharacterChoice)
src.CreateNewCharacter()
if (result == DeleteCharacterChoice)
src.DeleteCharacter()
src.ChooseCharacter()
else
var/success = src.client.LoadMob(result)

if (success)
del(src)
else
alert("I like cheese..")
src.ChooseCharacter()



Line 93 is :
var/result = input(src,"Character Creation", "DragonBall Zen") in menu
