Entry Price Error And ProtocolLib hook issues.

[RockStarTragedy]

I seem to be having trouble when trying to set property EntryPrice. I can set the value to something like 500 (I have tried with and without the dollar sign [$] ), but when a party is created and we try to pass through I get an error message "An fee of 500.0 rem is required." I have vault installed, and Essentials Economy is the only economy system I have, and that hooks into Vault, so I am used to currency looking like "$500" Am I missing something?

New Problem as of 10/6/15: I needed to add ProtocolLib in order for another plugin to function for my server. However, now when I try to edit command blocks I get a ton of errors pointing back to a failed dependency from instances to ProtocolLib.

"5.10 23:39:04 [Server] INFO at org.cyberiantiger.minecraft.instances.unsafe.depend.ProtocolLibPacketHooksFactory$PacketAdapterImpl.onPacketReceiving(ProtocolLibPacketHooksFactory.java:115) [instances-1.21.jar:?] 05.10 23:39:04 [Server] INFO java.lang.NullPointerException 05.10 23:39:04 [Server] INFO [23:39:04 ERROR]: [Instances] Unhandled exception occured in onPacketReceiving(PacketEvent) for Instances"

Is there any way to outright remove/prevent Instances and ProtoColLib from interacting with one another? Or something else I can do to edit command blocks normally without these errors popping up?
