Yes, in essence, this is what I need to report on.  I produce a cross-tab for each day.

The cross-tabs look something like the below:
CAT                                            134
DOG                                             67
OTHER                                         14
Total                                           215

There is one of these for each day in the range.  But I've only been able to do this for a set number of days.  I have set the report up, at this point in time, to go out (6) more days by way of subreports so that my final output would be (7) crosstabs.
12/1, 12/2, 12/3, 12/4, 12/5, 12/6, 12/7

I need to be able to break out each day in the range (whether it be for a week or month, etc.) in a separate crosstab.  The user needs to be able to analyze our kennel population from day to day.
