Need help with this script

[sujith.it]

Well, the script looks like fantasy.premierleague.com
It works like this: Our starting money is 100 milion. With that money, we must buy 15 players from 20 clubs available. We have to spend our 100 milion on 15 players. If we buy the player, our money will be dismished. For example : Our money is 100 million. Then I buy player named Gallas which is cost 6.5 million. So, our remaining money is 93.5 million. I only need that calculation script, so please help me to create it?
