Specific Ranks/Perms for specific worlds

I have a creative and a survival world on my server and i currently have survival ranks set up like
- Warrior
- Knight etc...
I'd like to setup building ranks for my creative world
-Builder
-AdvBuilder etc...

How do i set this up? so a player in the creative world will show his Builder rank and when in the survival world will show his warrior rank

Thanks

What permissions system are you using. Varies depending on the one you are using.

These are my plugins
Plugins (32): NoCheatPlus, WorldEdit, SimpleSignEdit, Vault, PermissionsEx, Multiverse-Core, CombatTag, Translate, WorldGuard, TreeAssist, BorderGuard, SpawnerAdjuster, iConomy, Register, Announcer, PaidRanks, CoreProtect, Lockette, PlayerStatusSigns, MobArena, mcMMO, SimpleClans, ButtonWarp, Essentials, Citizens, ChatManager, EssentialsSpawn, Multiverse-Inventories, Snowballer, ecoCreature, ChestShop, SimpleRegionMarket

You're using PermissionsEx. You would simply set up multi-world permissions. Instructions can be found on the wiki.

First time doing so, is this right?

Code:

groups:
  Guest:
    default: true
    permissions:
    - iConomy.payment
    worlds:
        homeworld:
            permissions:
            - test.example.node1
            prefix: '&f[Guest]&f('
        creative:
            permissions:
            - test.example.node2
            prefix: '&f[Builder]('

If it's wrong could you help me out?

Also how could i make it that players rankup by paying money automatically i have paidranks but it can only have 1 rank tree
