I don't think you should use $WBB{'format;DEFAULT'}.
Better use
$WBB{'formatNameDEFAULT'} = 'Short display';
$WBB{'formatHeadDEFAULT'} = "<CENTER><TABLE>
<TR>
<TD>Country</TD>
<TD> </TD>
<TD>Vintage</TD>
<TD>Wine</TD>
</TR>';
";
$WBB{'formatRowDEFAULT'} = '
$cc = ($rec{Country} ne "" ? $rec{Country} : " ");
$vv = ($rec{Vintage} ne "" ? $rec{Vintage} : " ");
" <TR>
<TD NOWRAP BGCOLOR=$rec{Color}>$cc</TD>
<TD NOWRAP>$ThisRecordIcons $ThisRecordBasket</TD>
<TD>$vv</TD>
<TD>$rec{Wine}</TD>
</TR>"';
$WBB{'formatFootDEFAULT'} = '</TABLE></CENTER>';
This is an extract of something I used for a friend who has a store selling
wine.
I show only four fields in the default format.
Good luck,
