Programming error that doesn't make sense to me : <p>I am writing a Java program where the user enters in a sales amount and then they enter a code(1, 2, or a 3) and then the program calculates the commission based on the sales type(the code the user entered). It works for 1 and 3 but for some odd reason when I enter in a 2 for the code it does nothing, just closes even though the code is pretty much the same as 1 and 3. Any help would be appreciated.</p>
