Please do yourself a favor and never use backslashes to escape double quotes in HTML, it's impossible to read. Use here-docs or plain qq{} and q{}, for example:

print qq{
  <td>
  <textarea NAME="reh_dinner_site_addins_lang"                     
            ROWS="4"
            COLS="46"
  >$row[50]</textarea>
  </td>
};
