javascript - ラジオ ボタンの検証により、残りの検証が失敗する

Question

無線の検証は機能しますが、残りは機能しません。私は何を間違えましたか？

function validateRadio(radios) {
    for (i = 0; i < radios.length; ++i) {
        if (radios[i].checked) return true;
    }
    return false;
}

function validateForm() {
    if (validateRadio(document.forms["pancettaForm"]["updateShip"])) {
        return true;
    } else {
        alert("Please tell us how you would like to update your order.");
        return false;
    }
}

var x = document.forms["pancettaForm"]["order-number"].value;
if (x == null || x == "") {
    alert("Please provide your order number.");
    return false;
}
var x = document.forms["pancettaForm"]["full-name"].value;
if (x == null || x == "") {
    alert("Please provide your full name, or the recipients name if you are updating shipping information.");
    return false;
}
var x = document.forms["pancettaForm"]["phone"].value;
if (x == null || x == "") {
    alert("Please provide a phone number in case of delivery questions.");
    return false;
}
var display = document.getElementById('address').style.display;

        return false;
    }

    if (document.pancettaForm.state.value == "- Select State -") {

        return false;
    }
