Issue with fetching records when SalesForce Date Fields involved

Question

Using the Events application of Salesforce I enter a record of data.  The record has a Start Date of Monday and an End Date of Friday for a given week.  Crystal will not fetch/display the record in the report.  If I go back and change the Start Date and the end Date to teh same day, the record will print in Crystal.
Is there some Date flag within Crystal that I need to toggle allowing a record to print based on date ranges?  I don't understand why a record would print when Start and End Date are the same but will not print when different?

Answer 1

Here is the code....  I have also noticed that there are three fields - Start Date, End Date and Due Date.  Only when all 3 fields are set to the same value within Salesforce will the record print in Crystal.  I have tried removing any reference to the Date fields in the crystal report but its not helping
