I have lots of examples that I printed from the Crystal knowledge base website. I have some reports where I call in 3 DBs and sort them by minutes and seconds to put the reports in order by how long it took to perform certain tasks. That's when I really had to work at it to get what I wanted. I was using start and end times and calculating time differences and graphing them. Whew! Hope you don't have to do alot of that.
