But I keep restoring the 2 original files after I make a mess... and it still does not work as before my mistakes. That's the part I cannot understand..

Im writing a validation class for ZC, (already finished but havent posted yet) you can have a look if you want.

https://svn.rubikintegration.com/zen...validation.php
For example, to check if the customers_email_address passed in POST is not empty and is valid email:

$yvalidation = new yvalidation();
$rules = array('customers_email_address' => array(array('validation_is_not_empty'=>''),
                                         array('validation_is_email'=>'')));
$yvalidation->set_params($_POST);
$yvalidation->set_rules($rules);
$error_counter = $yvalidation->run(); // store the number of errors here 

Multiple fields can be checked at once, each field can be checked against multiple rules.

Thanks, I will take a look..
for now I just did as follows (and it works for me):

      
 if(ereg('^[\s0-9]*$', $a-item1) === false){
    $error = true;
    $messageStack->add('silentauction', 'Leave empty, or enter only numbers (dollar amount, no cents) in your bid input box 1!)');
 }
if ($a-item1!='' && $a-item1<= 600){
  $error = true;
  $messageStack->add('silentauction', 'Your bid for Fall Buck is equal or bellow the reseved bid of $600!)');
}
