Collision only works with one clip?

programming flash

Okay, I’m sure this is a noob problem. But I have a collision going on between two clips, clip A and clip B. I tried to copy and paste clip A, but then clip B would only interact with one of them… not both.

Is there a way to get this to work with both? I tried adding clip A to an array, and checking for a collision with the array with

for(var i:uint = 0; i < TestArray.length; i++){
if (A.hitTestObject(TestArray*)){
do something

but it still only works with one of the clips. Any ideas? Thanks guys.
