Need help with pop up window using externalinterface. so close to finishing!

ight. i think i have actually made some progress!

I managed to get one button within the movieclip ‘myClip’ to work and open a pop up.

Now how do i add the functionality to the other buttons within same movieclip?

I thought i would just have to give them all different instance names, such as ‘link2’ , ‘link3’ etc.

Is this correct? If this is so, what else do I need to do?
Do I need to make to the code on the main stage timeline?

Im having a struggle with this bit. So close!!

Can you help?

A BIG Thanks if you can help me finish this off!
