Trying to write a report here and I hit a bit of a snag. I'm trying to create a report that shows incoming calls grouped by half hour for each day. Right now its only showing half hours where calls came in. I'm looking for a way to display every half hour. Even the ones where there is no calls.

Is there a way to display each half hour even if there is not a record for that half hour?

Thanks so much for ANY help,
