Crashing after closing form

Hi,

Am trying to run some simple code when user clicks OK but it crashes AutoCAD.  The OK button should run some code and close the form:

(defun c:CM_Admin/frmCMAdmin/txtButton_OK#OnClicked (/)
  (dcl-Form-Close CM_Admin/frmCMAdmin)
    (if logo_name
    (progn
      (insert_logo logo_name)
    )
  )
)

Sorry for these very basic questions but not getting very far.

I have go it working by setting the OK button return value to 3:

(dcl-Form-Close CM_Admin/frmCMAdmin 3)

Then check the return value when showing the form:

(setq return (dcl_Form_Show CM_Admin_frmCMAdmin))

(if (= return 3) (etc...

Hi, yes you are right: it's similar to the faq: http://www.opendcl.com/forum/index.php?topic=1080.0.
