Great. Thanks. That worked to get rid of the error there, but now when I clicked through to "book it" I get the following error on the "add reservation" pop-up:

Warning: Invalid argument supplied for foreach() in /home/XXXXXX/public_html/administrator/components/com_booking/helpers/booking.php on line 1269

When I try to click through to "save and go to checkout". I am redirected to xx.com/reservation/current.html, but only my home page is displayed with a message "Item was added to current reservation." If I look in admin, the reservation does not appear under the "reservation" section.
