problems deleteing deadbodies

[shark attack]

hi  im trying to get hozs delete dead body script  to work  with mission im making  but am having difficulties

the script

; Select the Unit
_unit = _this select 0
;-Delay the delete after death
~5
; Sink into the ground
_k = (getpos _unit) select 2
#loop
_k = _k - 0.1
_unit setpos [(getpos _unit) select 0,(getpos _unit) select, _k]
?(_k > -1):goto "loop"
; finally delete the vehicle
deletevehicle _unit
exit



the script works everytime  but i get error messages   eg

invalid no in expression  which i took to be the commer
(getpos _unit)select,_k
so i removed only to recieve different error message
error zero division

its a cool  script  and would like to use it   anyone see what im doing wrong
i have the line  this addeventhandler ["killed", {_this exec "dead.sqs"}]    in the init field of units i want  to disapear


any help will be apreciated

fixed it


altered script  so that unit dosnt sink  just disapears
itll do for me

put this in units init that you wish to delete afterdeath
this addeventhandler ["killed", {_this exec "dead.sqs"}]    

dead.sqs

; Select the Unit
_unit = _this select 0
;-Delay the delete after death
~10

; finally delete the vehicle
deletevehicle _unit
exit
