The grid effect problem

Hi well I did the grid effect and it worked fine but the problem is I want the grid(swf file) to load in the main movie I am doing. The problem is when I test it only a white box shows up. It doesn’t show the grid.

here it what I put in the key frame in the timeline

loadMovie(“grid 1.swf”, “container”);

it just doesn’t show. Is there something wrong I did. Can somebody give me a helping hand please.
