I have a question.

[Silver Knight]

For my PW, I wanted to create a 'Trade route' system. Nation can buy/take over trade routes, and set a tax for passing through. Trading through Trade Routes will play an important part in the server, as Traders sell goods to merchants, so that merchants can stock their stores.
I was having problem with the setting tax. I was wondering if anyone would be so kind as to teach me the commands needed to make it work. Stuff like when the playersays "Raise Taxes, 100" it would set the tax to pass through to 100g.
I'm not NAT or anything, but trying to get this done before friday. I would have my Head NAT script it, but he is grounded .

Thanks,
