I am designing a website on the Wix website. I have a dropdown form that contains five options $($these options represent the number of rooms the user can reserve$).$ The first option is one room, the second option is two rooms, the third option is three rooms, the fourth option is four rooms, and the fifth is five rooms. $.$

The maximum number of rooms a user can book is five rooms.

For example: If the user chooses the second option, he is reserving two rooms, which means that he has three rooms remaining that he can reserve $($for everyone, not local memory$).$

How can I do this and make the maximum number that a user can reserve is only five rooms, even if he tries to rebook from another user?
