It never hurts to include your code (provided it's not too long! O_O).

Just be sure to use code tags @_@

There ya go, im working on a calculator program =D

You can't declare a method within another method O_O

You'll have to pull all of your other methods (add, subtract etc) outside of the definition of your simp method. Your simp method can have the logic of the continuous play, but it can't have method definitions >_<
