Not sure if this matters, but in your select options, you have options such as 1,2,3,4,5,6 all of these are ints
so value = int
in your if statements, you are checking to see if the selection is equal to (String) "1","2","3","4","5",or "6".
Which isnt the same for example 6 != "6"
i would assume that once you click an option, either an exception occurs or nothing (i may be wrong) but throwing that out there haha 🙂
