Option value with forma action

Using option value in a form like this:

<form action="query.html"
method="GET" name="ventana">
<p>Indique la forma de pago:</p>
  <p><select NAME="Pago" size="1" >
      <option VALUE="metalico"> En metálico </option>
      <option VALUE="cheque"> Cheque </option>
      <option VALUE="transferencia"> Transferencia bancaria </option>
  </select>

it gets a output like this: “?Pago=metalico”. How can I get that output will be something like “metalico.htm”, that to say, without symbol “?”.

Thanks

Thi s worked for me. It had the option text, not a symbol.

I mean without the “?” symbol in the output
