You can create a page filter that will filter your published data/recordset to show records for the current day by following these steps:
1. Create a datefield on your form (use the common fields > date field as opposed to the calendar date field).
2. Within the Publisher, select the page and click Page Filter
3. Create a filter that reads "mydatefield = [today]".
The "[today]" value will be replaced with the current day. You can also use this with the datesubmitted field, to show, for example, only submissions from the current day.
