htp-package problem

I have the following procedure:

create or replace procedure htp_mult (pval varchar2 := '0') as
begin

   if pval = '0' then

      htp.print('<form>');
      htp.print('<action="http://adress/pls/verk/htp_mult");
      htp.print('method="post">');
      htp.print('<select name="wert" size=3 MULTIPLE>');
      htp.print('<option>one');
      htp.print('<option>two');
      htp.print('<option>three');
      htp.print('</select>');
      htp.print('<br><br><input type="submit" value="submit">');
      htp.print('</form>');
   else
      insert into test (erg, art) values (wert, 'option');
      commit;
      htp.print('Value '||pval||' inserted!');

now, if someone choose *more than one* value in the html-form, than I dont get [Quoted] these selected values, or better: I cant evaluate the multiple choice !!

does anybode know, how to make it within a plsql-procedure??

thanks in advance
