Getting unexpected end of file parse error...WHY?

jthunter24

I am very new to PHP and keep getting a parse error that says unexpected end of file. I have checked every curly brace, quotation mark, semi colon, and more and can't seem to find out what is causing it. Any help would be greatly appreciated!
<?php if(isset($_POST['calculate'])) { $errors =array(); $fname = $_POST["firstname"]; $fname = trim($fname); $fname = strtolower($fname); $fname = ucfirst($fname); $lname = $_POST["lastname"]; $lname = trim($lname); $lname = strtolower($lname); $lname = ucfirst($lname); $hworked = $_POST["hoursworked"]; $hwage = $_POST["hourlywage"]; //Validating empty elements if(empty($fname)) { $errors['fnameempty'] = "*"; } if(empty($lname)) { $errors['lnameempty'] = "*"; } if(empty($hworked)) { $errors['hoursempty'] = "*"; } if(empty($hwage)) { $errors['wageempty'] = "*"; } //Ensuring Fname and lname are at least two characters validateName($fname, 'fnamelength'); validateName($lname, 'lnamelength'); validateLongName($lname, 'lnamelong'); //Ensuring Hourrly wage is numeric and greater than 10 validateNumeric($hwage); validateWage($hwage); //Ensuring hours worked is numeric and does not exceed 60 validateNumeric($hworked); validateHours ($hworked); if(count($errors) == 0) { header("Location: success.php"); exit(); } else { $fname=""; $lname=""; $hwage=""; $hworked=""; { } //Functions function validateName($name, $short) { global $errors; if (!empty($name)) { if(strlen($name) < 2){ $errors[$short] = "must be at least 2 characters"; } } } function validateLongName($name, $long) { global $errors; if (!empty($name)) { if (strlen($name) > 25) { $errors[$long] = 'name cannot exceed 25 characters'; } } } function validateNumeric ($validate) { global $errors; if (!is_numeric($validate)) { $errors ="only numeric values are allowed"; } } function validateWage ($wageval) { global $errors; if ($wageval < 10) { $errors = "wage must be 10 or above"; } } function validateHours ($hourval) { global $errors; if($hourval > 60) { $errors = "hours must not exceed 60"; } } ?>
