@Cpt.Sparz Please read the OpenStudy code of conduct: http://openstudy.com/code-of-conduct

You did not guide the user to answers, you just gave them answers, which accomplishes very little. @SGTC! is in no better position to solve any of these problem types without outside assistance than when they started.
