Calling JavaScript from a SQL report?

Question

I am using the HTMLDB_ITEM api's to build my report. I am trying to render a text item and append an image / hyperlink to the end of my textbox which links to a custom popup page.
I have all this working but I need to use a JavaScript call html_GetElement to pass into the URL I am building in the link.
e.g.
This query works fine and my popup page fires passing the value 'ABC' into the element P323_PIN on the popup page 323.
<br><br>
SELECT HTMLDB_ITEM.text (01, NULL, 10, 25)
||
'<ah ref="javascript:html_PopUp(''f?p=&APP_ID.:323:&APP_SESSION.::::P323_PIN:ABCD'');
">Link</a>' pin
FROM DUAL;
<br><br>
PS the hyperlink tag has been broken so it will display in the forum.
<p>I would link to replace this with the value (if any) that the user types into the textbox (01).
Any suggestions as I cannot seem to concatanate the right value into my url string. I think it is due to the quotes but I cant see the wood for the trees at the moment.

If the at line selections is getting fired then just use this option to call the url,
REPORT  zkb_test4.
DATA: v_str(60) TYPE c.
AT LINE-SELECTION.
  DATA: v_url TYPE string.
  v_url = v_str.
  CALL METHOD cl_gui_frontend_services=>execute
    EXPORTING
      document               = v_url
    EXCEPTIONS
      cntl_error             = 1
      error_no_gui           = 2
      bad_parameter          = 3
      file_not_found         = 4
      path_not_found         = 5
      file_extension_unknown = 6
      error_execute_failed   = 7
      synchronous_failed     = 8
      not_supported_by_gui   = 9
      OTHERS                 = 10.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
               WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.
START-OF-SELECTION.
  v_str = 'http://sap.com'.
  WRITE / v_str.
  HIDE v_str.
