loadMovie stuff

Hi
With the following code I am trying to load redPic jpeg into the second frame of a movie called content. content has 2 key frames the firsts contains a graphic and the second is empty and waiting for redPic. when I play the movie redpic loads and my moviclip plays with red pic static as if it is in both the frames, rather than play the 2 frames with the two graphics alternating. I cant work out where red pic is sitting.

red_btn.onRelease = function() {
var i = 1;
loadMovie(“redPic.jpg”, _root.content_mc.createEmptyMovieClip(“red_mc”,1));
red_mc=_root.content_mc._currentframe + i;
trace(_currentframe+i);//this give the intended value of 2
};

I have used a varriable because i intend to bring lots of images by using a counting loop

I wonder if anyone can help or am I in the wrong ball park on this one.

Cheers
