I am attaching the user interface and the code for a Visual Basic Program I am trying to write as I try to learn this from a book. What is supposed to happen is the user is to enter a letter and click either food or animal. The output then depends on the letter entered and the item it corresponds with. The problem is, no matter what letter is entered or which button is selected, I always get the "Invalid Entry" message that is also part of the program. Please advise.
