How do I hide Not Avalaible time from the public?

Hi,
Please check the file
components > com_osservicesbooking > helper > calendar.php
find this source code
<table cellpadding="0" cellspacing="0" width="100%">
<tr>
<td style="font-size:11px;border:1px solid #F8A1AA !important;background-color:#FCF3F4;width:100%;padding:5px;">
<?php echo JText::_('OS_NOT_AVAILABLE_TIME')?>: <BR />
<?php
for($i=0;$i<count($tempEmployee);$i++){
echo $i + 1;
echo ". ";
echo date($configClass,$tempEmployee[$i]->start_time)." - ".date($configClass,$tempEmployee[$i]->end_time);
echo "<BR />";
}
?>
</td>
</tr>
</table>
and remove them.
Good luck
Dam
