First of all, are you sure this code works? perltidy reports that it parses this way: 
...
  $count = $dbh->do("INSERT INTO  ques (...) VALUES (...)",
                    undef,
                    $usernamenow,
                    $txtque,
                    ...
           );
...

I think you want single quotes for the SQL statement and placeholders (?) like this: 
  $count = $dbh->do('INSERT INTO ques (...) VALUES (?,?,?,?,...)',
                    undef,
                    $usernamenow,
                    $txtque,
                    ...
           );

You use of double quotes and string interpolation (i.e. using $usernamenow inside the double-quoted string) will definitely cause you problems.
