Since the call to Get_Left_Encoder_Count() does not reset the internal value, your local variable (lec) will saturate very quickly. Once the encoder moves one tick it will increment lec over 12 almost instantly. You either need to reset the value to 0 or use Get_Left_Encoder_Count() on its own as your counter.

do you mean set the "Get_Left_Encoder_Count()" function variable to 0? so your saying that Get_Left_Encoder_Count()" function variable holds its value every time it interrupts, even if I call it once and then call it again. that is definitely what Mr. Watson seems to have stated in his code. that makes sense, though I don't see how it holds the total value every time it interrupts without being declared as static.
