I DESPERATELY need some help on this for a plugin and Osclass 5.1.

This

at

<a class="btn"onclick="return delete_dialog('<?php echo $id; ?>');" href="<?php list($csrfname, $csrftoken) = osc_csrfguard_generate_token(); echo osc_admin_base_url(true).'?page=items&spam=delete&item='.$id.'&CSRFName='.$csrfname.'&CSRFToken='.$csrftoken; ?>"><?php _e('Delete Ad', 'spamprotection'); ?></a>

How can i fix this?
