Rentalot Plus calendar not working in Joomla 1.7

I've installed rentalotplus on a joomla 1.7 installation and did not have the calendar when checking for Availability.

It was working on a 2.5 installation but I've had to go back to 1.7 as the commumnity builder component would not install on 2.5

Here's an image of what was happening.

the solution is to log into the admin area.

Go to

> components

> rentalot

> configuration

> general

and then navigate down to the 'Site date picker' dropdown and change this. One of them should work for your site. For me it was JQuery
