Updating DWG Properties with AutoLisp

[tcoley95E9Z]

I made this program that takes 3 inputs for a custom DWGProps field, combines them, and then updates DWGProps accordingly. For some weird reason it seems to work fine the first few days but then I get this error:

The weird thing is if I type Regen in autocad, the dwgprops did in fact get updated. Any ideas? Code below, thanks!

(defun c:dProps () 
  
  (setq mmIn (getstring "\n Enter Month: ")) ;Input Month
  (setq ddIn (getstring "\n Enter Day: ")) ;Input Day
  (setq yyIn (getstring "\n Enter Year: ")) ;Input Year
  
  (setq dateVal (strcat mmIn "." ddIn "." yyin))

  (vl-load-com)
  ((vla-SetCustomByKey 
     (vla-get-summaryinfo 
       (vla-get-activedocument (Vlax-get-acad-object))) 
                     
        "Issue Date"  dateVal    ;First Field = Name // Second Field = Value                 
      ) 
  )     
  
 (command "-REGEN") ;Regen command to automatically show the updated props   
)

Your structure of parentheses is wrong - see the double "(" in:

((vla-set....

since you're running vl routines might as well replace:

(command "_.REGEN")

with this:
(vla-Regen (vla-get-ActiveDocument (vlax-get-acad-object)) acActiveViewport)

Good to know! Is this preferred just to keep a consistent code throughout or is it faster?

Thank you so much!

there are advantages at times to using vlisp functions instead of relying on command line like this:
