Bones move, mesh doesn't

(Keep in mind, this is my first extensive creation) I’m having quite a bit of trouble with rigging my character. I got the mesh done, got the skeleton done, removed duplicates on the mesh then added weights automatically. The first time I tried to, it gave me an error saying it couldn’t find the weights, then I removed duplicates and it didn’t give me an error, but it still won’t move the mesh with the bones. I can’t tell what I’m doing wrong, and I’d love to know. If you have any ideas, please let me know. Thank you for your time everyone!
