_aco.push(['VARIABLE_1', 'VALUE_1', 'VARIABLE_2', 'VALUE_2', ...]);
VALUE_n should be replaced by code that pulls the current user’s property value from your system. We can’t write it for you because we don’t have access to your system. For example, if your site uses PHP, the email call might look like this:
_aco.push(['email', '<?php echo $current_user->email ?>']);
VARIABLE_n can be any of the below.
