This is the basic setup, don't mind the \v text codes, I was using a text code to help test it, also I'm gonna make some custom windows, and then use that to display how much Gold is in the bank, but you guys can just ignore the \v texts(unless you're using Yanfly's message script, then by all means. Yanfly's message script is a script everyone should really use, It allows you to bypass a major restriction).
It all works perfectly, enjoy.
