Hey, I have a suggestion on revising the bank script though I still haven't tried it.
So the problem is what if the player has $999,998? Maybe we should go on to checking I'd say something done in a programming language Idk how to do it in script though (Maybe we can use an asm routine to solve all the things by using the callasm etc. etc.).
First put the no. of money the player has to a variable. If you know basic VB Programming Language you'll understand this.
