Question on Database

I have a question about a problem I am having on a mysql db. I have inherited a website from someone that I can no longer get in touch with. The website is a smaller version of Monster.com it allows user to submit a resume and search jobs online. I am having errors on it but I am not sure I have it all. Should it have a *.sql file? It has only phtml,inc files also a admin area and all the images. I am getting an error on index.phtml of: Warning: Supplied argument is not a valid MySQL result resource in C:sitessitesindex.phtml on line 7 and : Warning: Supplied argument is not a valid MySQL result resource in C:sitesdocsma.inc on line 7 line 7 of index is: $copy = mysql_fetch_array($return); line 7 of ma.inc: $meta_row = mysql_fetch_array($meta_return); Please help . Thanks..
