How to paint foliage on a landscape?

I’m having issues with the tutorial for painting grass on a landscape. I set up everything how the tutorial said to but it’s not working.

Is there any way to fix this? What am I doing wrong?

From what i can see in your pictures you are on the landscape edit tool rather then the foliage edit tool, you want to go across another tab to the right and that will take you to the foliage tool which will allow you to paint foliage onto your terrain.

You will need a grass static mesh of some description to use the foliage tool though.
