What's wrong with this attach code

Hello everyone

I have some problem about this lisp code

I want to attch DWG file to autocad map 3d

when I run code it was prompt this error

This is a error prompt:

>>Command: LLMS_ATTACH_CHAN

>>Querying from M:\LLMS_CAD\Parcels\Chanthaboury.dwg ...

>>Executing property query...done.

>>Executing location query...done.

>>Displaying queried objects...

>>611 object(s) have been queried.Unknown command "LLMS_ATTACH_CHAN". Press F1 for help.

This is my code:

(defun c:LLMS_ATTACH_CHAN (/ ade_cmddia_before_qry echo ortho dwgname dwg_id)

   ;store system variables
   (setq ade_cmddia_before_qry (getvar "cmddia"))
   (setq echo (getvar "CMDECHO"))
   (setq ortho (getvar "ORTHOMODE"))
   ;set system variables
   (setvar "cmddia" 0)
   (setvar "CMDECHO" 0)
   (setvar "ORTHOMODE" 1)

   (ade_projsetwscode "UTM84-48N")
   (setq dwgname "M:\\LLMS_CAD\\Parcels\\Chanthaboury.dwg")
   (if (/= nil dwgname)
       (progn
      (setq dwg_id (ade_dsattach dwgname))
                   (ade_dwgactivate dwg_id)
	    (ade_qryclear)
	    (ade_qrysetaltprop nil)
	  
                   (ade_qrydefine '("" "" "" "Location" ("all" )""))
	    (ade_qrysettype "draw")
                   (ade_qrydefine '("AND" "" "" "property" ("layer" "=" "Chanthaboury") "" ))

	    (ade_qryexecute)
                   (ade_qryclear)

                   (command "_zoom" "e" "")
        )
             (alert "Can't attach the drawing")
    )
 ;restore system variables
 (setvar "cmddia" ade_cmddia_before_qry)
 (setvar "CMDECHO" echo)
 (setvar "ORTHOMODE" ortho)
(princ)
)

Change:

(command "_zoom" "e" "")

to:

(command "_zoom" "_e")

That's true
