File DataBase problems...

[worldspawn]

I downloaded a simple and small File DataBase for my website. When I add a file using the admin fuction there is one small problem... It gives me this message when I try to add a file and put the link for where the file is being kept.

You have an error in your SQL syntax near 'WHERE category_id=1 num_files=num_files+1' at line 1

What do I have to do to fix it?

'WHERE category_id=1 AND num_files=num_files+1'
