LISP missing a line.

I have the code below to place a block on a point. Then array that block based on information given by the user. Then move all of the blocks so that the insertion point is the top and center of all the blocks. It works fine sometimes but about half the time it it skips the first move command. Could someone tell me what I am missing?

(DEFUN C:COMEDARRAY ( / OLDL NOR NOC CEB CEP )
 (SETQ OLDL (GETVAR "CLAYER"))
 (COMMAND "_LAYER" "SET" "ELEC-CE" "")
 (SETQ NOR (GETINT "\nENTER NUMBER OF COMED ROWS: "))
 (SETQ NOC (GETINT "\nENTER NUMBER OF COMED COLUMNS: "))
 (setq CEP1 (getpoint "\nPICK INSERT POINT FOR BLOCK: "))
 (COMMAND "_INSERT" "S:\\LightSett\\LISP FILES\\LISP USED BLOCKS\\COMED PROFILE.DWG" CEP1 "" "" "")
 (SETQ CEB (ENTLAST))
 (COMMAND "_ARRAY" CEB "" "R" NOR NOC 0.6667 0.3333)
 (SETQ CEP (SSGET '((0 . "INSERT"))))
 (COMMAND "_MOVE" CEP "" CEP1 (cons (- (CAR CEP1) (/ (* NOC 0.3333) 2)) (CDR CEP1)))
 (COMMAND "_MOVE" CEP "" CEP1 (LIST (CAR CEP1) (- (CADR CEP1) (* NOR 0.6667)) (CADDR CEP1)))
 (command "layer" "set" OLDL "")
 (PRINC)
 )

Be sure that the layer is exist and unlocked

is your block always new to your drawing or is it sometimes allready present? In that case autocad will add extra prompt if you want to redefine this block. You might want to check if block is present with tblsearch or use -insert blk=s:... or use expert variable

Since the code in the OP uses command calls the problem is likely caused by the OSMODE setting. To avoid undesirable object snapping when using command calls you can either temporarily change the OSMODE setting to 0 or use this principle:

(command "_.move" ss "" "_non" pt1 "_non" pt2)

@Roy,

Was thinking the same thing,

I also had some weird behaviour caused bij OSNAP in the past.

You're probably right and it was my first thought also but OP stated it (totally?) skipped move command so that's why it would have been my second suggestion :-)

Keep your osmode simple and save the defuns in your library lisp if you have one then you call it in every routine with a simple (oszero) (osold) (osx 512) or add to Acaddoc.lsp.

(defun oszero ( / )
(setq oldsnap (getvar 'osmode))
(setvar 'osmode 0)
)

(defun osold ( / )(setvar 'osmode oldsnap))

(defun osx (x / ) (setvar 'osmode x))

Thank you all, it was my osnap. I should have thought of that, that is what I get for trying to code when I am tired.
