I only get this error when I add a row to the form using
$form->addHTML('<tr><td>'.$voorstelling.'</td><td> </td><td>'. $aVoorstelling['speeldagen_datum_tijd'] . '</td></tr>');
The row displays properly and the HTML seems well-formatted.
If I don't include the row, the form validates and the OnCorrect function fires and all is well.
Can you please tell me what is going on? I cannot figure this out with my limited knowledge of FormHandler (I inherited this application). I think we're using FH3.
