There's a reason for the Preview button -- it's to confirm that what you're posting is readable and has the minimum ;) number of spelling mistakes.

Now on to reviewing your code.

Update: Sorry, pressed submit too soon. It looks like you are missing the part that pulls the data from the database -- you need something like $row_array->{$name_of_data_element_goes_here} in your table cell.
