Welcome Ali :) I'd like to help, but I don't really understand your issue. Just to get it right: You want to create 1 comp by 2 other comps to get all in one? If yes, make sure the comp above has an alpha channel (transparency). Maybe you could add a screenshot... Anyway, enjoy video.se!

If you mean that you have two compositions in one main composition, and you want both to show their contents on **top** of each other, then I can help you.

Make sure that you click on "Toggle Switches / Modes",

so that you have the "Mode" option available.

Now set the top composition to either "Screen", "Add", or "Lighten".

Make sure that the top composition has at least some transparent part in it, if it's just a full solid black layer, nothing's going to show through be default, unless you lower the opacity down.
