Visual Basic Online Restaurant Menu

[FredB]

Hello, I am fairly new with Visual Basic and I am wondering how I can add variables to certain menu options, in order to create sort of like a receipt after adding the total (including tax)

-I need help with variables in combo boxes and radio buttons and giving them values (and eventually adding them together)

-I need help coding certain buttons, one to add the total of the selections to the receipt, and another one to clear the selections, as if going to the next pizza in this case

Any help would be greatly appreciated, thanks
