Enter data then submit it. You'll see my error. Here is my code as of now:
<html>
<head>
<title>Your answers</title>
</head>
<body>
<center>
Mean= <?php echo (($_POST[data1]*$_POST[1freq])+($_POST[data2]*$_POST[2freq])+($_POST[data3]*$_POST[3freq])+($_POST[data4]*$_POST[4freq]))/$_POST[points]); ?>
<br>
</center>
</body>
</html>
Just view the sources of the data entering page if you think that's the problem but I dont see it could be.Mean= <?php echo (($_POST[data1] * $_POST[1freq]) + ($_POST[data2] * $_POST[2freq])+ ($_POST[data3] * $_POST[3freq]) + ($_POST[data4] * $_POST[4freq])) / $_POST[points]; ?>
