Now I am struggling with how to declare the average variable and have it calculate my average. I commented out some of the things I have tried.
<?php
// get the data from the form
$first = filter_input(INPUT_POST, 'first');
$last = filter_input(INPUT_POST, 'last');
$one = filter_input(INPUT_POST, 'one',
FILTER_VALIDATE_FLOAT);
$two = filter_input(INPUT_POST, 'two',
FILTER_VALIDATE_FLOAT);
$three = filter_input(INPUT_POST, 'three',
FILTER_VALIDATE_FLOAT);
//$Average = float ($one + $two + $three)/3;
// validate Score one
if ($one === FALSE ) {
$error_message = 'Score one must be a valid number.';
} else if ( $one < 0 ) {
$error_message = 'Score one cannot be less than zero.';
// validate Score two
if ($two === FALSE ) {
$error_message = 'Score two must be a valid number.';
} else if ( $two < 0 ) {
$error_message = 'Score two cannot be less than zero.';
// validate Score three
if ($three === FALSE ) {
$error_message = 'Score three must be a valid number.';
} else if ( $three < 0 ) {
$error_message = 'Score three cannot be less than zero.';
// set error message to empty string if no invalid entries
} else {
$error_message = ''; }
// if an error message exists, go to the index page
if ($error_message != '') {
include('index.php');
exit();
}
// calculate the average score
//$Sum = $one; + $two; + $three;
//$Average = $Sum / 3;}}
$Average = ($one + $two + $three)/3;}}
//$Average = ($one + $two + $three)/3};
$Average = number_format($Average, 2);
?>

I have some type of syntax error I can't find. I was thinking it was or something like that but comparing to my sample code from class I can't see what I am missing. Is it jumping out to anyone else?
I have reviewed the brackets and I'm not seeing what I am doing incorrectly. I have compared it to my classes source code and am scratching my head. I used a validator and it isn't showing any errors.
<?php
// get the data from the form
$one = filter_input(INPUT_POST, 'one',
FILTER_VALIDATE_FLOAT);
$two = filter_input(INPUT_POST, 'two',
FILTER_VALIDATE_FLOAT);
$three = filter_input(INPUT_POST, 'three',
FILTER_VALIDATE_INT);
// validate Score one
if ($one === FALSE ) {
$error_message = 'Score one must be a valid number.';
} else if ( $one < 0 ) {
$error_message = 'Score one cannot be less than zero.';
// validate Score two
if ($two === FALSE ) {
$error_message = 'Score two must be a valid number.';
} else if ( $two < 0 ) {
$error_message = 'Score two cannot be less than zero.';
// validate Score three
if ($three === FALSE ) {
$error_message = 'Score three must be a valid number.';
} else if ( $three < 0 ) {
$error_message = 'Score three cannot be less than zero.';
// set error message to empty string if no invalid entries
} else {
$error_message = ''; }
// if an error message exists, go to the index page
if ($error_message != '') {
include('index.php');
exit();
}
// calculate the average score
$Average = ($one + $two + $three) / 3;}
