Object ID for area field

I am currently working on an autolisp command that will make an area field for a polyline. I have figured out everything except how to get and use the object id. I keep getting an error:

bad argument type: stringp 2128026136

That number is the object id, but I can't get the command to use it tho.

Can someone help please?!?!?!

here's the command:

(defun c:ASF (/ ent)
(command "undo" "g")
(setq olderr *error*)
(defun *error* (errmes)
(princ
(strcat "\n Area (Sq. Ft.) by Polyline halted by: \n"
errmes
)
)
(command "undo" "end")
(setq *error* olderr)
(command "undo" "1")
(prin1)
)
(vl-load-com)
(PROMPT "\n\nArea (S.F.) by Polyline....\n")
(setq setosm (getvar "osmode"))
(setvar "osmode" 16384)
(setq ent (vlax-ename->vla-object (car (entsel "pick"))))
(setq objidlwpoly (vla-get-objectid ent))
(setq atfield
(strcat
"%<\\AcObjProp Object(%<\\_ObjId "
objidlwpoly
">%).Area \\f \"%lu2%ct4%qf1 SQ. FT.\">%"
)
)
(command "mtext" pause pause atfield "")
(vlax-release-object ent)
(setvar "osmode" setosm)
(command "cmdecho" 1)
(setq *error* olderr)
(command "undo" "end")
(princ userobjid)
(princ)
)

 

strcat expecta a string.

(itoa objidlwpoly)
