Selection set could very well be called: today

5 eqf @td

would be the selection if 5 is a date and you want it to match todays date.

This is a great kind of selection table to create.  It will always pick today. 
Downside.  You need to run the report on the date required.  Tomorrow will be 
tomorrow.
