Duplicated movie clips on wrong layer

Hello all. I have some code that has hearts falling from top to bottom and randomly float off the screen. The problem is the layer order. I have the code tucked under a layer of some text, but the hearts end up covering up the text. So would this be a depth problem? What would be some code to tell the newly duplicated movie clips what layer to appear on(as in appear below the text layer in the timeline).
