SELECT DISTINCT and COUNT

I'm trying to write a query for an access database to give me distinct dates letters were sent out and the number that were sent out that day, and I'm having some trouble. My SQL book gives the following example:

Code:
SELECT COUNT(DISTINCT DateSent)
FROM Mailings

COUNT(DISTINCT DateSent)


To which access says syntax error.

Can anybody help me out? Thanks!

swampboogie, i can't believe you slipped up, you are usually perfect

"distinct dates" --> return more than one row

"number sent that day" --> number sent each date
Code:
select DateSent, count(*) 
  from mailings
group
    by DateSent
