# HTML Validation errors – rowspan is null

 * When doing a W3C HTML validation check on my WordPress site, the timetable plugin
   is throwing errors:
 * **Bad value for attribute rowspan on element td: The empty string is not a valid
   non-negative integer.**
 * Here is a snippet of HTML in relation to this with rowspan attribute not set:
 * <td class=”mptt-shortcode-event mptt-event-vertical-default” data-column-id=”
   49″ rowspan=”” colspan=”1″ data-row_height=”45″ style=”height:45px;”>
 * If it helps, this is the shortcode I am using:
 * [mp-timetable title=”1″ time=”1″ sub-title=”1″ row_height=”45″ increment=”0.5″
   view=”none” label=”All Events” hide_label=”0″ hide_hrs=”0″ description=”1″ hide_empty_rows
   =”1″ group=”1″ disable_event_url=”1″ text_align=”center” text_align_vertical=”
   default” id=”” custom_class=”” responsive=”1″]
 * I cannot find where the rowspan attribute should be defined, any help?

 * It’s fixed in version 2.1.10. Update your plugin.
