I have the following form:

And the JavaScript part so far is calculating the health and energy from the three fields body, mind, and soul.

the function:

<script type="text/javascript">
function handle(a,b,c) {
			var e = document.getElementsByTagName('input');
			for (i in e) {
				if (e[i].name == a) a = e[i];
				if (e[i].name == b) b = e[i];
				if (e[i].name == c) c = e[i];
			}
			c.value = (Number(a.value) + Number(b.value)) * 5;
		}

</script>

the form:

<form action="insert.php" method="post">
<table border="0">
  <tr>
    <td>Body:</td>
    <td><input type="text" onKeyUp="handle('body','soul','health')" name="body" size="10" maxlength="2"></td>

I need some help with a way to alter the current function or writing a new function if necessary, to calculate the acv1 and dcv1. The formula for acv1 is [(Body+Mind+Soul)/3] (rounded down or floored I think it is called), and the dcv1 is [(Body+Mind+Soul)/3] (rounded down) - 2.

Can anyone help me out here?

I found a way to do it:

function yearOfBirth ($day, $month, $age)

    $now = strtotime('1992-03-23');

    $yob = date('Y', $now) - $age;
    
    if (date('md', $now) < sprintf('%02d%02d', $month, $day)) $yob--;
    
    return $yob;
}

$year =  yearOfBirth($_POST['birth_date'], $_POST['birth_month'], $_POST['age']);

//store our posted values in the session variables
$_SESSION['identity'] = $_POST['identity'];
$_SESSION['name'] = $_POST['name'];
