Problem with speed

I have created a aircraft compass which rotates 360 degrees and a counter which shows the reading of the compass. The speed of rotation of compass is 2. I am not much adept with actionscript so I have created a movie clip for the counter which reads backwards and forwards on press of two invisible buttons on a selector knob. One button each for clockwise (and forward movement of the counter) and anticlockwise (for backward move of the counter) movement of the compass. However, even after a lot of trial and error I am unable to synchronise the counter with the compass even though it works fine. Can anyone tell me what the rotation speed of 2 signifes. If I use a frame rate of 12 how can I synchronise the counter and will changing the frame rate help.
