Give this a try:
<?php comment_form(
array(
'fields' => apply_filters( 'comment_form_default_fields', $fields ),
'comment_field' => '<p class="comment-form-comment"><label for="comment">' . __( 'Comment', 'jenny' ) . '</label><textarea id="comment" name="comment" cols="45" rows="8" aria-required="true"></textarea></p>',
'comment_notes_before' => '<p class="comment-notes">' . ( $req ? __( ' Required fields are marked <span class="required">*</span>', 'jenny' ) : '' ) . '</p>',
'comment_notes_after' => '<p class="form-allowed-tags">' . sprintf( __( '', 'jenny' ), '' ) . '</p>',
'id_form' => 'commentform',
'id_submit' => 'submit',
'title_reply' => __( 'Leave Your Comment', 'jenny' ),
'cancel_reply_link' => __( '(Cancel Reply)', 'jenny' ),
'label_submit' => __( 'Submit', 'jenny'),
)
); ?>
That might work, if I’ve done it correctly,
Thank you Otto.
