Form Validation

[Vanecelli]

The below code is checking for a a "checked" radio button, but no matter what the form will stop on the first Button set, checked or not. Basically, it's not recognizing whether or not the button is checked because it always stops at the first set. What do I need?

function validate(what)
 
{
    var valid = true;
 
    for (var i=0, j=what.elements.length; i<j; i++) {
        etype = what.elements[i].type;
    id = what.elements[i].name;
 
if (etype=="radio") {
            if (what.elements[i].checked==false) {
            what.elements[i].focus();
            what.elements[i].style.background = "red";
            switch (id) {
                    case "Rankbutt": 
                        alert('Please select a branch for accurate Rank selection');
                        valid = false;
                        return valid;
                        break
                    case "pay": 
                        alert('Please select a payment method');
                        valid = false;
                        return valid;
                        break
                    default:
                        alert('Please ensure the form is completely filled');
                        valid = false;
                        return valid;
                }
 
            }
        }
    }
