User Post Delete Issue

Greetings, I’m trying to allow users to delete their posts, and I’m trying to do that with the;

$or_pid = get_the_ID();
if(isset($_REQUEST['p_id']) && $_REQUEST['p_id']>0){
        wp_delete_post($_REQUEST['p_id']);

}

and

<div class="tbl_col"><a class="delt" href="<?php echo get_permalink($or_pid); ?>&p_id=<?php echo $post->ID; ?>">Delete</a></div>
        </div>

but it’s not working. You check the whole code from http://pastebin.com/VWN21GNZ
I’d be grateful if you can help me.
