i need help fixing this.it shows "Saiyin has logged in!" which it suppose to show the character's name.

here's the character name input part. as you can see, my character name variable is CHARNAME and mob will be /mob/M
------------------------------------------------------------
mob/proc/CreateChar()
var/mob/M
var/CHARNAME = input("Please use appropriate names or I will ban you. You can put in any names but don't put in any names that may offend ones race, gender, or in any other way.", "Create A Character")

if("Saiyin")
M = new /mob/Saiyin()
....bunch of other working codes
....bunch of other working codes
....bunch of other working codes
....bunch of other working codes
....bunch of other working codes
....bunch of other working codes
....bunch of other working codes

src.client.mob = M
M.CHARNAME = CHARNAME
M.loc = locate(5,5,2)
del(src)
-----------------------------------------------------------



here's the load character turf and proc
------------------------------------------------------------
mob
proc
LoadChar()
var/savefile/F = new("players/[src.ckey].sav")
var/X
var/Y
var/Z
var/mob/NewCharMOB = new()
F["name"] >> name
F["X"] >> X
F["Y"] >> Y
F["Z"] >> Z
F["Mob"] >> NewCharMOB
NewCharMOB.loc = locate(X,Y,Z)
src.client.mob = NewCharMOB
del(src)


turf/LoadChar
Click()
if(fexists("players/[usr.ckey].sav"))
usr.LoadChar()
world << "\[[world.name]]--> [usr] has logged in!"
usr << "Welcome back to the game!"
return ..()
