In my second post I said posting pictures of code isn't that helpful. Since I can't read what comes before your recent pic (e.g. was db declared anywhere, or is it still at the top of your module?). Or is it that "utility" doesn't exist as spelled? Or is it that rs is no longer declared or is out of scope? I have suggested posting an up to date db and/or code instead of pictures but haven't convinced you it seems. Hope you find a solution.
