Help with telltarget

I could really do with some help on a telltarget command subject!

I have this main move which is index.htm and in the flash movie I have an MC called (stage) when I press a button it loads a swf file into stage.

However what I want to do is have a fade out sequence i.e. frame “finish” when this movie stops I will set a var as say play=1;

So I need my main nav to detect var play has reached 1 then play finish and load the next movie into stage!

Here is my code so far, but i think ive got it all wrong!!!

on (release)
{
if (play==1) {

stage.gotoAndPlay (“main/finish”);

// I want it to fade out the current movie and then load the next .swf file below!!

loadMovie(“flash/cont.swf”, _root.stage);

}else{

// if no movie has been loaded into stage yet play will not = 1 so just play this swf anyway.

loadMovie(“flash/cont.swf”, _root.stage);
}
}

“main” is the scene of the current movie and finish is my fade out sequence.

On the current movie I set play like this

play=1; //is this right?

I hope I have made some sense.

Many thanks for your guys help in advance!!
