02 columns on the main page

The changes are not only the files, you need to update database also. And quite a lot files need to be update. So i think, you had better to install the update version.
Thanks

oh my god.

that would be mean i need to redo all my template design all over?
can u come out with some template solutions? preserve changes to template something ??

Can you let me know what are the files that you have changed? i will let you know how to update the OS Property.
Thanks

com_osproperty\classes\category.html.php
com_osproperty\templates\default\listing.html.tpl.php

you only need to backup 2 files :
com_osproperty\classes\category.html.php
com_osproperty\templates\default\listing.html.tpl.php
And after install the update, you can edit the file listing.html.tpl.php

Add this js function line 15 to 24:
... language="javascript"
function loadStateInListPage(){
var country_id = document.getElementById('country_id');
loadStateInListPageAjax(country_id.value,"<?php echo JURI::root()?>");
}
function changeCity(state_id,city_id){
var live_site = '<?php echo JURI::root()?>';
loadLocationInfoCity(state_id,city_id,'state_id',live_site);
}
....

And from line 184 to 204.
<td width="50%" align="left" style="border:0px;font-weight:bold;">
<a href="<?php echo JURI::root()?>index.php?option=com_osproperty&task=property_changelayout&viewtype=2&url=<?php echo JURI::current();?>">
<?php
echo JText::_('OS_CHANGE_TO_GRID_VIEW');
?>
Good luck

}else{

}
echo JText::_('OS_OF');
echo " ".$pageNav->total;
?>
