Hi List,

I've

-------- snip -----------
<form action="[process-order]" method=post target="warenkorb">
  <input type="hidden" name="mv_session_id" value="[data session id]">
  <input type="hidden" name="mv_nextpage" value="ord/basket">
  <input type="hidden" name="mv_todo" value="refresh">
  <input type="hidden" name="mv_order_item" value="[sql-param artintnr]">
  <input type="hidden" 
onClick="document.forms[0].action='[process-order]'" name="mv_click" 
value="buy">
<tr>
<td>
<input type="text" class="stueck" size="1"  name="mv_order_quantity" 
value="1" maxlength="2">
</td>
<td class="klein">&nbsp;St&uuml;ck in den Warenkorb</td>
<td>
<input type="image" src="wk_symbol.gif" width="20" height="16" alt="" 
border="0" name="buy">
</td>
</tr>
</form>

Any tips, helps and hints are very welcome.

Thanks!

Joachim
