I am new to crystal reports but I have a pretty solid sql background as well as vb6 and asp.  Here is my question:

how do I get a formula field to return a number,  and then increment itself by one if a date falls in a certain range?  Here is what I want to do in a formula field:

If {RegistrationMaster.Use Date} >= {@BegDate} and {RegistrationMaster.Use Date} <= {@EndDate} Then  increment the value by of this field by one

Thanks!
