[Plugin: WTI Like Post] how to show like/dislike in one number?

Hi,
I was wondering if you could point me out where do you print out the like and dislike numbers. I can quickly do a subtraction of both and print a new number out. This would resolve my question.

thanks

this is what I have. However, the unlike still showing “+” in front the unlike value. Thanks

global $wpdb;
     $show_symbols = get_option('wti_like_post_show_symbols');
     $wti_unlike_count = $wpdb->get_var("SELECT SUM(value) FROM {$wpdb->prefix}wti_like_post WHERE post_id = '$post_id' AND value <= 0");
     $wti_like_count = $wpdb->get_var("SELECT SUM(value) FROM {$wpdb->prefix}wti_like_post WHERE post_id = '$post_id' AND value >= 0");
     if(!$wti_like_count) {
		$wti_like_count = 0;
     }

	 if(!$wti_unlike_count) {
		$wti_unlike_count = 0;
     } else {
		if($show_symbols) {$wti_unlike_count;
		} else {
			$wti_unlike_count;
		}
     }

	 if($wti_like_count != $wti_unlike_count){

   if($wti_like_count > $wti_unlike_count){$wti_like_final = $wti_like_count - $wti_unlike_count;$wti_like_final = "+" . $wti_like_final;}
   else{$wti_like_final = $wti_unlike_count - $wti_like_count;$wti_like_final = "-" . $wti_like_final;}
   }
   else

   {$wti_like_final = '0'; }

	  return $wti_like_final;
