The Client Information Screen automatically opens to a 'new' record.  From here, you simply need to start filling in information for a new client.  The 'Contact ID' filled will be AUTOMATICALLY populated.  Note that the 'Age' is calculated from the 'First Contact Date' minus the 'Birth date' fields.  This is to ensure that the Statistical Analysis that runs against the 'Age' query is accurate for the Age the client was when you FIRST saw them, not necessarily their current age.  As such, the 'Age Range' pull down menu allows you to adjust their statistical age range should you see them again in the distant future and want to ensure your statistics are accurate for the year or month in which you run them.
