<form name="liq_CFLmeasures">
  <tr class="valores">
    <td align="center" class="dato">2009-04-13</td>
    <td align="center" class="dato">2009-04-131310</td>
    <td width="20" align="center">
    <label>
       <input name="CFLw0" type="text" id="CFLw0" size="1" maxlength="1" value="3" onChange="T_CFLw0.value=(CFLw0.value*F_CFLw0.value  ).toFixed(2)" >
    </label>    </td>
    <td align="right">
    	<label>
          	<input name="F_CFLw0" type="text" id="F_CFLw0" size="6" maxlength="6" onChange="T_CFLw0.value=(CFLw0.value*F_CFLw0.value  ).toFixed(2);" onFocus="Sumar();" onBlur="NoSumar();" >
        </label>    </td>
 
    <td align="right">
    	<label>

        </label>    </td>
    <td align="right">

<script type="text/javascript">
function Sumar(){
      interval = setInterval("calcular()",1);

function calcular(){
 
	A = document.liq_CFLmeasures.T_CFLw0.value;
 
	B = document.liq_CFLmeasures.T_CFLw1.value;
 
	C = document.liq_CFLmeasures.T_CFLw2.value;
 
    document.autoSumForm.L_CFLw.value=(A * 1)+(B * 1)+(C * 1);

function NoSumar(){
      clearInterval(interval);
}
</script>
 
<tfoot>
	<th colspan="4" scope="col" class="grande" >Total by CFL Measures</th>
    <th  class="titulo"><label>
 
    	<input name="L_CFLw" type="text" class="total" id="L_CFLw" value="0.00" size="8" maxlength="8"  readonly >
    	</label> </th>
</tfoot>
</form>
 
este es el codigo
no se si este obligado a ponerlo en el header lo cual seria un problema porque como digo se genera en PHP luego de crear los campos correspondientes
 
Resumido lo que necesito es esto
 
CFLw0 * F_CFLw0 = T_CFLw0
CFLw1 * F_CFLw1 = T_CFLw1
CFLw2 * F_CFLw2 = T_CFLw2
 
Al final deseo se sumen en L_CFLw todos los T_CFLw
 
 
Saludos
