1493605 - How to modify existing Crystal Reports formulas using the CR SDK for VS .NET

• Modifying Crystal Reports formulas allows for a more flexible report
• Formulas are always stored internally as a string
• Using the wrong syntax when assigning a string variable to a formula will result in errors
• A typical error would be: “a number is required here”
