Rainy_Day Posted May 25, 2010 Share Posted May 25, 2010 This looks an awful lot like homework, and we disallow threads asking for help on such topics. Closing this, if you wish to discuss it with me via PM, feel free to drop me a message. ( ͡° ͜ʖ ͡°)RIP Michaelangelopolous Link to comment Share on other sites More sharing options...
