I am tring to create a foliage mask that appears on my soil layer 
and i am unable to grow any grass on the soil layer. I am using the 
latest 
version of Unreal. I have attempted all recommended solutions, yet I 
still cannot get it to function. This is quite frustrating. Does anyone 
know why this is not appearing? I have been following a tutorial and 
everyone has the same issues.

Ah, you did
basically you want to eliminate as many variables as possible - if you stick a constant 1.0 into Landscape Grass and it generates grass then you know the issue lies in one of your masks.
if it does not generate grass then you know something more sinister is wrong.
fwiw.. habitually, I use a weightmap with no material assigned for grass and subtract from it in my material - I can't remember why I started doing it but it means I can paint grass out manually if I need to.
