>What's that little trick using the recno() and MOD (I think) to do something to every other row in a report? How would I apply that to changing the colors of the background box? Would I need to have two boxes and use the Print When for each?

I depends on your data ... some others have suggested RECNO() as the expression, but that won't work if you're using an index. If you're using an index, use a report variable. Define rnCount, doesn't matter what the expression is, set the calculate option to Count, reset it at the end of the page. Then use can use MOD(rnCount,2)=0 and MOD(rnCount,2)<>0 in the Print When for the two different colored background boxes.
