flash actionscript: Hi

I'm using code in my first frame to position a mov containing 3 sections into
the right place. Example of code;

Code:
btn2.onRelease = function() {
var club:Tween = new Tween(movs, "_x", Regular.easeOut, movs._x, -632, 1,
true);
_root.movs.portfolio.gotoAndPlay("startport");
};
I then have a portfolio section which has external swfs loading into an empty
container and then moving to the second frame. In the external swf I have a
back button to get back to the portfolio screen with the following code;

Code:
on (release) {
import mx.transitions.Tween;
import mx.transitions.easing.*;
_root.container.unloadMovie("port-shimano-carp.swf");
_root.gotoAndStop("home");

var club:Tween = new Tween(movs, "_x", Regular.easeOut, movs._x, -632, 1,
true);
_root.movs.portfolio.gotoAndPlay("startport");

}
Which unloads the movie, then goes back to frame 1. And thats it. Rather than
then pushing the movie strip to the right position. Am I right in thinking that
because its going to the first frame its then not reading the rest of the
code?? If so, is there a way round this, and is it possible??

If it helps the files are downloadable from here;

I'm still a bit new to actionscript, so any help would be greatly received.

Do you mean this bit?

var club:Tween = new Tween(movs, "_x", Regular.easeOut, movs._x, -632, 1,
true);
_root.movs.portfolio.gotoAndPlay("startport");

}

I changed it to;

var club:Tween = new Tween(_root.movs, "_x", Regular.easeOut, _root.movs._x,
-632, 1, true);
_root.movs.portfolio.gotoAndPlay("startport");

}

But with still the same result

i looked and that's too messy to go through carefully. i can see this is a
problem, though:

gotoAndPlay("_root.movs.portfolio.cat-port");

which should probably be:

_root.movs.portfolio.gotoAndPlay("cat-port");

I've changed that bit too, still the same. Thanks for your time...
