-----I need help with logic bricks PLEASE!!----

so im trying to make it so that mesh A turns to mesh B turns to mesh C turns to mesh D and so on, im using the delay trigger to do it but i cant seem to get it to work, if your confused with what im talking about just open the blender file, it should be self explainatory.

what i was trying to do is manually put simulated liquid into a game engine, it seems pretty strait forward but im finding it difficult.liquid in game.blend (356 KB)
