It means exactly what it says: you concatenated or stringify an undefined value. Looking in your code (of which I do not know exactly where it starts, so line 42 is a bit of a guess) it can be either print qq(<td bgcolor='#d0d0d0'>$_</td>); or print qq(<tr><td colspan=$columnspan bgcolor='#d0d0d0'> </td></tr>); In the latter case, please check $columnspan to be sure it is given a defined value. For the first: you go through a list of tablerow values, can it be that a value is NULL? This would be translated into undef and hence raise this warning. Try to replace with my $val=$_||'NULL'; print qq(<td bgcolor='0#d0d0d0'>$val</td>); --Frank -- Reporting bugs: http://perl.apache.org/bugs/ Mail list info: http://perl.apache.org/maillist/modperl.html
