SlideShow Module errors

I can't get the Ossolution Properties SlideShow Module to show anything.
The frame shows up with the following errors:

Above:
Warning: Invalid argument supplied for foreach() in /homepages/38/d246175369/htdocs/vsix/modules/mod_ospropertyslideshow/helper.php on line 139
At the top within the frame
Warning: Invalid argument supplied for foreach() in /homepages/38/d246175369/htdocs/vsix/modules/mod_ospropertyslideshow/tmpl/default.php on line 29

I have set the data source with three properties using the ID numbers.

Hi,
They are only warning of php, no dangerous, but it seems there aren't any properties in the slideshow. Can you please send me your site information with super admin account to my email. I will check for you.
Thanks
Dam

I have sent info at damdt@joomservices.com

Hi Dam,

Slideshow module still doesn't work for me.
You should have already the access to the site (including ftp). Could you have a look?

You should select cities for all your properties if you want to show them in the slideshow.
Thanks
Dam
