I don't quite follow.
looking at the offered page, you have applied the offGrid access rule which is defined as
allow if user lever in group offGrid
offGrid has members defined as:
you can access that page when logged in as level 4 because 4 is a member of the access group that page uses.
"This is where my problem is. I want level 5 to be able to get into levels 1-4, but i don't want levels 1-4 to get into level 5. How do I put that."
it doesn't really work that way.
pages that you want to be accessed by levels 1-5 create a rule with an access group for levels 1-5
pages that level 5 should not be able to access, don't add level 5 to access group.
