i know its not the most efficient, but the answer it's giving is too low for some reason, it works with the test data but not on the real data

Looks like you attempted to use a command? Please note that we only use slash-commands on this server 🙂

Try starting your message with a forward-slash / and Discord should open a popup showing you all available commands.
A command might then look like /foo 👍
