[Resolvido] Não somar campos desabilitados

[TiagoMaker 3]

Dae pessoal, tenho um formulário onde cadastro varios produtos, somando a quantidade e o valor unitario para gerar o valor final, mas as vezes pode ser que não sejam inseridos todos os produtos que são listados por checkbox, e então eles não precism ser somados, com meu javascript atual se eu não preencher todos os campos fica aquele "NaN" exibido.

 

desabilita campos não selecionados

function Hab(valor){
var check = eval("document.cadastro.C"+valor)
if (check.checked) {
var campo = eval("document.cadastro.T"+valor+".disabled=false"); eval("document.cadastro.T"+valor+".focus();")
var campo = eval("document.cadastro.X"+valor+".disabled=false"); eval("document.cadastro.X"+valor+".focus();")

} else {
var campo = eval("document.cadastro.T"+valor+".disabled=true");
var campo = eval("document.cadastro.X"+valor+".disabled=true");
}
}
function Desabilita(){
for(i=0; i<document.forms[0].elements.length; i++)
if(document.forms[0].elements[i].type=="text"){
document.forms[0].elements[i].disabled=true;
}
}

soma os campos:

 

<script type="text/javascript">
function Calc(){
Valor1 = parseFloat(document.getElementById('vunit1').value);
Qt1 = parseFloat(document.getElementById('qt1').value);
Valor2 = parseFloat(document.getElementById('vunit2').value);
Qt2 = parseFloat(document.getElementById('qt2').value);
Valor3 = parseFloat(document.getElementById('vunit3').value);
Qt3 = parseFloat(document.getElementById('qt3').value);
Valor4 = parseFloat(document.getElementById('vunit4').value);
Qt4 = parseFloat(document.getElementById('qt4').value);
Valor5 = parseFloat(document.getElementById('vunit5').value);
Qt5 = parseFloat(document.getElementById('qt5').value);
Valor6 = parseFloat(document.getElementById('vunit6').value);
Qt6 = parseFloat(document.getElementById('qt6').value);
document.getElementById('resultado').value = (Valor1*Qt1+Valor2*Qt2+Valor3*Qt3+Valor4*Qt4+Valor5*Qt5+Valor6*Qt6).toFixed(2);
}
</script>

Dae galera! Consegui fazer o procedimento, consegui colocar campo a campo, com soma aumatica, e em moeda! Vou compartilhar a função com voces!
