cara usa Java Script pra resolver... toma um codigo ae... wink.gif

basta você chamar ele no seu form:

<form action="nome_pagina" name="FormNome" onSubmit="return checa(this);">

CODIGO:

<script>

function checa(nform) {

//validacao de radio buttons sem saber quantos são

marcado = -1

for (i=0; i<nform.NOME_DO_RADIO.length; i++) {

if (nform.NOME_DO_RADIO.checked) {

marcado = i

resposta = nform.NOME_DO_RADIO.value

}

}

if (marcado == -1) {

alert("Selecione uma resposta.");

nform.NOME_DO_RADIO[0].focus();

return false;

}

return true;

}

</script>
