Selecting Authorize.net does not work

[ Moderator note: title adjusted, please refrain from using help, urgent, emergency, asap, etc. in topic titles. ]

Once I have selected a test room that costs 1$ click a link that takes me to my cart, i verify it is the room I selected and click checkout. that loads the checkout page where I enter my “customer details” The only payment method I have available is “Authorize” the authorize.net payment method (I installed the plugin that came with wp hotel, it is checkmarked as active, sandbox mode is off, and proper credentials are inputted). Once I agree to terms and hit checkout the next page is my cart, but my carts empty and my booking has been made? There is no place to input credit card info. We are launching this week I need help on this.
