I am trying to make a Windows Form in VS 2010 that is used to determine whether someone is entitled to a prize/medal/award whatever you want to call it. So basically if someone clicks on a check box to say they attended an event and they enter a date range between saying they attended the event between 01/01/2010 - 01/02/2010 and the requirement for the award is that they attended the event for more than 20 days then because the statement is true I would want a box to pop up and say person is entitled to receive a particular award. There are multiple awards available based on different conditions so to be eligible for so the result would be dependent upon which boxes and date ranges are selected.So For Award1 the logical argument is something along the lines of
IF Event1CheckBox = Checked AND Attendance => 20 Result = Entitled to Receive Award1 Else = Not Entitled To Receive Award1
