When I'm trying to run this through Netbeans it shows notice errors, but the form is displayed correctly and works fine. Why could it show the errors?
<html>
<head>
<title>Form Validation with Multiplication</title>
</head>
<body>
<?php
if(!empty($errors))
{
echo join('<br />', $errors);
}
elseif(isset($_POST))
{
$value = ($_POST['number1'] * $_POST['number2']);
echo 'The Multiplication is: '.$value.'<br />';
}
?>
<form method="post" action="">
Enter the Number 1 <input type="text" name="number1" value="<?php print $_POST['number1']; ?>" size="5" maxlength="5" /><br />
Enter the Number 2 <input type="text" name="number2" value="<?php print $_POST['number2']; ?>" size="5" maxlength="5" /><br />
<input type="submit" name="submit" value="submit" />
</form>
</body>
</html>
