Booking widget not fuctioning?

Hi..
I am using a booking widget on my own site. I have it set to allow children. I have it in my rules to allow children. All rules,etc are applied to my property. HOWEVER...

The picture attached is what I get when I tested it out before adding the widget to my site-

Any ideas, suggestions to fix this would be greatly appreciated.

Didn't click one button under amenities. Problem solved.

Thank you for posting this!   Had this same issue.    Under Amenities I had to change this field:  Children >= 2 yo
