I need help from you crystal reporting experts!! I made a slight modification to a crystal report that had been working fine, but when I tried to run it, I got an error message that I don't recall seeing before: "Invalid Procedure Call or Argument". When I reverse what I did, I still get the same error message. Do any of you have any idea about what it is referring to and how do I fix it?
