Playing MC from targeted SWF

hi I am trying to play a MC called (play), in a loaded swf called BOX.SWF. but the button is situated in BOX2.SWF.
I v tried for a few hours to resolve it, tried a number of approaches and script techniques.

any advice is appriciated, thanks in advance:0

if any master can help, plse!!!

Is this what you needed??

thats the same file that I posted???

I need the button in BOX2.SWF to play the movieclip PLAY, within BOX.SWF.
heres a better file to use.

hi all,
does this make sense??
I have three levels. the first file is OPEN.
the top button in OPEN loads a file called BOX.SWF.
the button in BOX loads another swf called BOX2.

From here you are given the third button(lower lefthand side)
if you press this button it should play a movieclip called PLAY. that is situated in BOX.SWF.

its purely an exercise to solve a problem that will determine the options that open from level 3, but exist in the first or second. this is because on unload of the third level, i dont want the movieclip to disapear???

sorry for any confusion

Sorry, on the open button, put this:

on (release) {
_root.targetone.loadMovie(“box.swf”);
}

I’m not sure if this answers all you questions, but this will make the movie clip “play” play.
