Excluding an effect from a Layer

Excluding an effect from a Layer

Excluding an effect from a Layer

Hey I seem to have trouble figuring out how to do this, here's an example.

I have 3 layers, 1 is a text layer, the other two are movie files. layer 2 overlaps layer 1 using the Alpha channel, but I want layer 2 to also use "Difference" mode or invert the color of layer 3 (the text layer), but if I set that mode on layer 2 then it will also do that effect to layer 1, so it also does "Difference/invert" to layer 1 also, and I only wanted it to do that to layer 3.
