Help with modifyworld PEX.

Hey there,
I am currently making a pixelmon adventure server, and need for when a player join to be able to interact with items (user a pressure plate) but NOT be able to place or destroy blocks.

So i tried these permissions.
newtrainer:
permissions:
- modifyworld.*
- -modifyworld.blocks.interact.107
- -modifyworld.blocks.place.*
- -modifyworld.blocks.destroy.*
users:

I now cant break blocks. BUT still can't use pressure plates or things. I also have a feeling I would also not be able to break blocks even if i hadnt added -modifyworld.blocks.destroy.*
The error message i get is : You are not permitted to interact with STONE_PLATE in red.
If you could post what i should do that would be great!

Thanks! I really hope you guys can help.

EDIT: I cant throw pokeballs either in rank newtrainer.
