Your syntax looks fine, but the warning probably indicates that the
variable ( $sth_display->{NAME}->[$c] ) is undefined. Check it with
defined() and print out ' ' or something if it isn't defined.
i.e. ( using trinary conditional operator )
defined( $sth_display->{NAME}->[$c] ) ? print
"<td>$sth_display->{NAME}->[$c]</td>" : print "<td> </td>";
should get rid of the warning;
