Galera peguei um script de carrinho de compras em js e adcionei alguns campos a ele, só que ele não soma o valor total dos items,
a parte do código está abaixo, se eu mandar exibir a variavel fields[7]
ele exibe o preco de cada produto, mais como eu faço pra somar todos?

eu coloquei essa variavel num alert, ai se tiver 10 items no carrinho ele exibe 10 alerts, cada um com o valor unitario de cada item.

if ( bDisplay ) {
         strOutput += "<TR style='border: 1 solid #000000'><td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='15' width='1'><b><font size='1' face='Arial Black'><a href='#' onClick=\"RemoveFromCart('+i+')\"><img border='0' src='images/tri-right1.gif' width='8' height='8'></a></font></b></td><td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='45'><font face='Arial' size='1' color='#000000'>"  + fields[0] + "</TD>";



         if ( fields[5] == "" )
            strOutput += "<td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='170'><font face='Arial' size='1' color='#000000'>"  + fields[3] + "</TD>";
         else
            strOutput += "<td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='45'><font face='Arial' size='1' color='#000000'>"  + fields[3] + "</I></TD>";

         strOutput += "<td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='45'><font face='Arial' size='1' color='#000000'>"+ fields[1] +"</font></TD>";
         strOutput += "<td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='28'><font face='Arial' size='1' color='#000000'>"+ fields[4] + "</TD>";

        if ( fields[5] == "" )
            strOutput += "<td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='55'>"  + fields[5] + "</TD>";
         else
            strOutput += "<td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='60'><font face='Arial' size='1' color='#000000'>"+ fields[5] + "Qunatidade_ta_aqui</font></I></TD>";

  if ( fields[6] == "" )
            strOutput += "<td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='20'>"  + fields[6] + "</TD>";
         else
            strOutput += "<td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='60'><font face='Arial' size='1' color='#000000'>"+ fields[6] + "</font></I></TD>";

 if ( fields[7] == "" )
            strOutput += "<td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='50'>"  + fields[7] + "</TD>";
         else
            strOutput += "<td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='11'><font face='Arial' size='1' color='#000000'>"+ fields[7] + "Valor_total</font></I></TD>";
if ( fields[8] == "" )
            strOutput += "<td style='background-color: #D8D8D8; border-style: outset; border-width: 2' width='55'><font face='Arial' size='1' color='#000000'>"  + fields[8] + "</font></TD>";

         strOutput += "<TD CLASS=\"nopentry\" ALIGN=CENTER></TD></TR>";
      }

Tem como postar a solução? Estou tentando montar um tipo de combo, onde tenho os produtos selecionados, ao desmarcar o produto que faz parte do combo pre selecionado o js teria que mudar o valor do combo.
