Start off by making the merchant then the booth (do this in anyway) then add a button that will open a modal popup make it say something like merchant and the two call to actions being the types it is selling and not what I did but cant come up with anything better so I’m doing it anyway for example it would be selling zappers and wooden wands so make a series of banner popups with the call to action primary label being but (Insert Price Of Item) and the Secondary Call to Action saying next. So the way it would work is link a wire between the banner and a vending machine and make it so when Primary Call to Action is clicked Attempt to Purchase and eventually it should look like this (somewhat)Sorry about the bottom its not finished
