Custom scripts

Hi, since im new, I have question about importing custom scripts in trinity core, becouse I’m getting some errors while doing that. If someone is willing to help, I would be grateful to him!
Have already downloaded file .cpp and the sql query for import. Just need some help with it, how to import it, and make it work fine.
Thanks in advance.

If they are old scripts very likely you will need to pay someone to fix them for you.

Hm, will check it. Thanks for reply
