Assuming you mean cartesian, you would need to use the filter and sort options in the portal to constrain to data that was modified today, and sorted how you wanted.
Build a script that finds today's records, sums everything you need into $$Globals and put them as merge fields in the footer of that List layout.
+1 for the cohort zone.
Sorry stupid spell check. Yes cartesian is what i meant.
I tried that mike and it doesnt work. There has to be simple way to display on a report what records were added today.
"I tried that mike and it doesn't work"
What exactly did you try?
Do you have a "date modified" field in your table?
Are you filtering based on a calculation of - table::dateModified = get(currentdate) ?
Do you have a sample of your file or screenshots you can post so we can advise further?
I figured it out mike. My Date field was set to a timestamp field. So the time was throwing off the calc. Thanks for your help.
