PHP Fatal error: Call to a member function on a non-object in

[valley]

Hello,

Many thanks for this nice contribution.

 

However I keep getting a PHP fatal error on line 74 and 34

 

PHP Fatal error: Call to a member function on a non-object in /home/affili43/affili43-www/catalog/wholesale.php on line 74

 

$messageStack->add('contact', ENTRY_EMAIL_ADDRESS_CHECK_ERROR);

 

if ($messageStack->size('contact') > 0) {

 

Where is 'contact' declared ?

 

Many thanks in advance for your help.
