external swf preloader in nested movie clip

[ROYOW]

Hello all,

Does anyone know how to create external swf preloader in a nested movie clip?

For example, clip_mc was loaded on a empty movie clip on the stage. There is another movie clip, clip_child_mc, will be loaded into another empty movie clip in clip_mc when a button is pressed. I hope my explanation is clear enough and hope to hear some feedback from you guys.

Thanks!
