Hola todos

No sé nada de Javascript, armé esto leyendo los FAQ.
Funciona bien salvo para el campo email.
Este es mi form:

Código HTML:

 <form action=viewtrans_user.php method=post name=form>
		<table align=center>

                <tr>

				<td colspan=4 align=center>

		</table>
	</form>

Y esta es mi función para validar:

Código PHP:

  function valida_envia(){ 
    //valido from_date 
    if (document.form.from_date.value.length==0){ 
        alert("Please enter a valid From Date") 
        document.form.from_date.focus() 
        return 0; 
    } 
 
    //valido from_month 
    if (document.form.from_month.selectedIndex==0){ 
        alert("Please enter a valid From Month") 
        document.form.from_month.focus() 
        return 0; 
    } 
 
    //valido from_year 
    if (document.form.from_year.selectedIndex==0){ 
        alert("Please enter a valid From Year") 
        document.form.from_year.focus() 
        return 0; 
    } 
 
    //valido to_date 
    if (document.form.to_date.selectedIndex==0){ 
        alert("Please enter a valid To Date") 
        document.form.to_date.focus() 
        return 0; 
    } 
 
    //valido to_month 
    if (document.form.to_month.selectedIndex==0){ 
        alert("Please enter a valid To Month") 
        document.form.to_month.focus() 
        return 0; 
    } 
 
    //valido to_year 
    if (document.form.to_year.selectedIndex==0){ 
        alert("Please enter a valid To Year") 
        document.form.to_year.focus() 
        return 0; 
    } 
 
    //valido email 
    if (document.form.email.selectedIndex==""){ 
        alert("Please enter a valid EMail") 
        document.form.email.focus() 
        return 0; 
    } 
 
    //el formulario se envia 
    //document.form.submit(); 
    document.form.submit(); 
} 
</script>

Por favor alguien podría decirme por qué no valida email ?
Muchísimas gracias

---Estoy editando

Ya ta, lo encontré. No validaba porque no es un SELECT.
Entonces sería para el campo email:

Código HTML:

//valido email
	if (document.form.email.value==""){
		alert("Please enter a valid EMail")
		document.form.email.focus()
		return 0;
	}

Perdón, ya me voy
