Does the incount++ action actually happen? I mean, when you check if the "if" statment is true, does the Microprocessor increase the valuce of incount? If it doesn't work, this should be done in a for loop, but if this "if" statment counts as a loop, then OK (it's just a method of a loop i've never seen before ).
