Maybe there's the problem? You're selecting the column 1 and i don't know is it possible to create column names like this. But maybe write there id or name something like this.

And i'm not sure if mysql_num_rows right there or not. I don't script MySQL since 1 month on Pawn, have forgot a lot of things.
