>Does anyone know where I can find a Tutorial on setting up a Report with Side by Side Multiple Detail Bands?

Take look at www.report-sculptor.com

It is not an easy/straight forward thing but it can be done.

You will have to rebuild your report content using either form and form controls (containers/labels/textboxes etc)
and drive report from code.

BTW I never had such requirement, so it would be interesting to do one of these for RS samples section. If you send
me test data and exact report layout/specs + permission to publish report layout itself (mock or obscured data), I will try to do it myself and send you resulting code.

However if there is some near deadline involved then you might be out of luck here. :(
