Detecting a collision with the child MC

hi im doing a wheel of fortune, and i need my pointer/ticker to detect which part of the wheel it has ‘touched’ and give a result at the end. so i decided to use hitTest but realise there is some problems with the ticker being on scene one and the my ‘hitTest brushes’ MCs being inside the wheel. So i cant make the ticker/pointer have a collision with each other? any one can help? if in doubt i will be more then willingly to explain it.:party:
