Dynamic radio button validation-- need help urgently

[plange]

HELP! I have a survey where the questions displayed on the site are dynamically pulled from a database and each question has a series of radio buttons. Each question needs to be answered and I thought this would do the trick but it isn't:

<!--
function checkQuestions(which) {
// require at least one radio button be selected per question
for (i = 0; i < which.length; i++) {
if (which.element.checked != true) {
alert(&quot;Please answer every question on this page.&quot;
}
}
return (false);
}
//-->

the function is obviously being called when form is submitted-- any ideas?!

I've revised the js but still no go:

function checkQuestions(which) {
// require at least one radio button be selected per question
isValid = false;
for (i = 0; i < which.length; i++) {
if (which.element.checked) {
isValid = true;
} else {
isValid = false;
break;
}
}
if (not isValid) {
alert(&quot;Please answer every question on this page&quot;
}
return (isValid);
}
