Looks like your question has pretty much been answered. But I'll add a side note to it.
Whenever your unsure about something (especially how a command works) go ahead and check out the help files. If it only has one argument to the command (e.g. deposit <amount> where deposit is the command and <amount> is the argument) means that you can type whatever you want afterwards, but the game only sees the first argument. Keep that in mind if something doesn't quite work the way you think it should.
