#name errors

Hi, I am not an excel specialist in anyway.  I am a real estate developer and someone had sent me a pro forma done on excel for a specific project.  I like the spreadsheet but I think maybe with some updates to excel or some things I played around with it doesn't work anymore.  Can i send it to someone and they fix the errors and also maybe highlight where I can input data to make changes?  I tried using excel with chatGPT and disaster isn't the word
