(solved) Keep getting error saying code not found or assigned to another phone

I’ve been trying to install Ratio for about 2 days now but I keep getting an error Every time I put my code in saying that it’s not found. Any help would be great!

I just figured it out, i didn’t realize i needed to include the “-” at the beginning of the code. mods feel free to take this post down, but i feel it may be helpful if anyone else has the same question.
