Setting a container to LoadMovie

I have tried creating a swf file with a button at bottom. Then created a shape 400px by 250px then converted to movieclip. I placed the movie clip on the scene at top with instance “container”.

Now i created a seperate swf file with a scene size the same as the movie clip. made a short animation and exported.

Back to my first swf file i added to the button:

on (release) {

Now that seems to work when i click the button, but it isnt loading it in the same place as the container instance??? why? its off to the right somewhere.

help please…
