Because you are getting the dates in string format (not the easiest way to do it, but reliable), you will also have to convert the strings to dates.<br>The format for dates in Crystal is DATE(YYYY,MM,DD) where YYYY, MM, DD are integers. So if your parameter is a string in the format "2000/02/24", you would convert this to a date in a Crystal formula by extracting the integer values for the date from the string.<br>DATE(ToNumber(?FromDate[1 to 4],0), ToNumber(?FromDate[6 to 7],0), ToNumber(?FromDate[9 to 10],0))<br><br> <br> <p>Malcolm Wynden<br><a href=mailto:wynden@island.dot.net>wynden@island.dot.net</a><br><a href= > </a><br>
