Using DAO I cant get a filter to work for dates..

First question, is posting just NOW into a date/time field for access mdb if I want to search just by date later down the road?

Second I just can't get it to work except for literals, which doesn't help me.

I've tried using the datevalue converted mentioned in MSDN and everything so.. anyone can help me please?

How can I apply the filter for a day that the user can pick or by a range?
