I have a MC that has a BTN inside. I duplicated this MC 20 times. So when I put actionscript on the button inside the MC it takes effect on all 20 MC’s. This is a problem because each MC is suppose to load a different jpg on release. Although I needed to duplicated these MC’s b/c they have a nice rollover effect which i have to use on all of them.

So what I tried to fix this was giving each MC it’s own instance name and then on the main timeline going “btn1.onRelease = …”. The problem with this is that the rollover effect on the button stops working. The rollover effect was happening because the btn inside the MC has a animation in it’s "over"state. But that is not being read with I put that above script on my main timeline.

Anyone had this problem before or know of a solution?
