the problem lies around this isset not working properly, i've tried to weeks to figure it out to no luck

PHP Code:

//    this conditional handles the confessing
 // guest handling
             if ('confess' && $confession_submit && trim($message) != '' && $bbuserinfo[userid] >= 0) 
             { 
 
                 if (isset($nousername)) //code won't work
                 {
                     $conf_userid = "NULL";
                 }
                 else
                 {
                     $conf_userid = "$bbuserinfo[userid]";
                 } //end annoying code that won't work
 
                 if ((time() - $check[timestamp]) <= 15)
                 {
                     eval("standarderror(\"".fetch_template("confession_error_flood")."\");");
                 }
                     $DB_site->query("
                         INSERT INTO confessions SET
                         text  = '".addslashes($message)."',
                         userid = '$conf_userid',
                         timestamp   = '".time()."'
                     ");
                     $url = "../confessions/";
                     eval(print_standard_redirect("confess_thanks"));
             }
             else
             {
                 $url = "../confessions/";
                 eval(print_standard_redirect("confess_error"));
             }
