>I need to print a total Hours and Minutes on a group break of a report. The table I am reporting from has a "Total minutes" field. What's the best way to do this from within the report?

I once had a report which had to show area in square kilometers, hectars and ars (1 ar=100 m2). I had a report variable, which calculated like this:

TotalM2 as sum of square meters. Expression to print: mod(TotalM2, 100)
Expression to print for hectars: mod(int(totalM2/100), 100), for km2: int(totalm2/10000).

Now for this you may just replace 100s for 60s to get minutes and seconds (if you're having seconds). If you've having more grouping levels, you may need to have more variables totaling the minutes for each level (like TotalMinutesInnerGroup, TotalMinutesOuterGroup, TotalMinutesWholeReport).
