@persalteas: If you press Enter, it is executing again from the homescreen, not relooping. Your code is looking for the [Clear] key.
[clear]=15
[enter]=9
If you want, try to put a Pause 20 in there before the Repeat loop and see what happens

@Yeong: I think it doesn't work because I programmed If, Repeat, and While to not affect Ans
