A novice programmer trying to complete a Restauran Menu Calculator in Visual C# 2010

[TheJoker1990]

Hi, I need to create an application that can be used in a restaurant to calculate a table’s bill. The program should display all the menu items from the table below in 4 Combo boxes. There are 4 categories of food offered which are Beverage, Appetizer, Main Course and Desert. Each Combo box should carry one of the food categories. The user can choose from the Combo box to add an item to a table’s bill. When each item is selected from the Combo box, the item price will be added to the bill. The Clear Bill button allows user to reset the Subtotal, Tax and Total to 0.Use 10% as the tax rate. To answer any future questions, Yes it is a school assignment and No i dont expect anybody to do the assignment for me. I already did part of the code or all of it, I am no really sure since I am just coding what i had learn so far in class and by reading the textbook. My question is what do i need to do next if anything, I debug the code already and it does compile, the menu items appear on the combo boxes, but it doesnt give me the total and the clear bottom doesnt do anything, this is what i got so far:
