Create a program to calculate how many alcoholic beverages to buy for a party

I run a wedding website, and want to offer visitors a quick and easy way to figure out how much alcohol they need to buy for their wedding.? Here is what I know: **Alcohol BuyingGuidelines** **A general rule of thumb is toprovide your guests with two drinks per person for an afternoon wedding and ? five drinksper person for an evening affair.? ? ** A bottle of Champagne = 7 drinks A bottle of wine? = 5 drinks A beer = 1 drink A liter of liquor = 18 drinks \---|\---|\---|\---|\---|\---|\---|\---|\---|\---|\---|\---|\---|\---|- If you are having a full bar, use thefollowing buying guidelines per 100 people: Beer = 2 cases (48 beers) Champagne = 1 ½ cases (18 bottles) Red wine = 1 case (12 bottles) White wine = 1 ½ cases (18 bottles) Whisky = 1-2 liters Bourbon = 1-2 liters Gin = 2 liters Scotch = 3 liters Light rum = 1 liter Vodka = 6 liter Tequila = 1 liter Dry vermouth = 2 bottles Sweet vermouth = 2 bottles \---|\---|\---|\---|\---|\---|-- TASK FOR CODER: I need a program where visitors can click on boxes that say whether they are having a day time or night time wedding (2 drinks per person or 5), how many people they are having, and what they want to serve (wine & beer or a "full bar"). ? I want the program to tabulate what you should buy to the nearest bottle.? Should be compatible with Drupal. Can be in HTML.
