Interaction Between Action Script3.0 and TimeLine Objects?

HI! i am developing a simple bowling game and new to actionscript3.0 i am facing problems

1# I have created a movie clip out side the time line and when i add the created movie clip to the stage its x and y coordinates are different and

2# problem is when my bowling ball hit the pins then i use if conditions and access to the time line animations like gotoAndStop(“thisanim”) , gotoAndPlay(“thisanim”) but when i use some nested conditions like if force is greater then this then gotoAndPlay(“this anim”) but it is not working well please guide me through that i am using it right or i am missing something that i don’t know about actionscript3.0.

I want some good Advice about this specially on interacting with Time Line using Action Script.3.0

Thanks in Advance…
