if (isset($_POST['submit_booking'])){
if (empty($_POST["cust[name]"])) {
    $nameErr = "Name is required";
    $errorFound++;
  } else {
        $name = test_input($_POST["cust[name]"]);
        if (!preg_match("/^[a-zA-Z ]*$/", $name)){
            $nameErr = "Only letters and whitespace are allowed.";
            $errorFound++;
   }if($errorFound ==0){
    $_SESSION['CUST'] =  $_POST['cust[name]']; 
   }
}
}

you're missing to close a semicolon for if (isset($_POST['submit_booking'])){
