Restructing a SQL query reporting 7 and 30 day counts to reporting daily counts over 15 days:

Hello, I have a query with the code:
SELECT Imported.[Modified By],
Count(1) AS UserCount,
(Select Count (*) from Imported) AS TotCount,
Round([Usercount]*100/[TotCount],2) AS Userpercent,
Sum(IIf([Date Modified]>Date()-7,1,0)) AS Last7Days,
Sum(IIf([Date Modified]>Date()-30,1,0)) AS Last30Days
FROM Imported
WHERE (((Imported.[Modified By]) Is Not Null))
GROUP BY Imported.[Modified By];

which reports to me several counts of user progress in a database (total, 7 and 30 day counts).   I would like to modify the code so that I can report a histogram reporting the number of records reviewed by a user over each of the last 15 days (i.e Day 1 user reviewed 10 records, Day 2 user reviewed 0 records, day 3 user reviewed 3 records etc... [only a sum of the records reviewed that day[).  Does anyone know how I should set up this SQL query to address this problem?  Bonus points if you can get the fields to be called by their appropriate name (i.e. Day 1 = January 2, 2011 Day 2 = January 3, 2011 etc...)

Thanks so much for any comments,
Bevo

Fixed this myself:

DaSELECT Imported.[Modified By],
Count(1) AS UserCount,
(Select Count (*) from Imported) AS TotCount,
Round([Usercount]*100/[TotCount],2) AS Userpercent,
Sum(IIf([Date Modified]=Date()-14,1,0)) AS Day14,
Sum(IIf([Date Modified]=Date()-13,1,0)) AS Day13,
Sum(IIf([Date Modified]=Date()-12,1,0)) AS Day12,
Sum(IIf([Date Modified]=Date()-11,1,0)) AS Day11,
Sum(IIf([Date Modified]=Date()-10,1,0)) AS Day10,
Sum(IIf([Date Modified]=Date()-9,1,0)) AS Day9,
Sum(IIf([Date Modified]=Date()-8,1,0)) AS Day8,
Sum(IIf([Date Modified]=Date()-7,1,0)) AS Day7,
Sum(IIf([Date Modified]=Date()-6,1,0)) AS Day6,
Sum(IIf([Date Modified]=Date()-5,1,0)) AS Day5,
Sum(IIf([Date Modified]=Date()-4,1,0)) AS Day4,
Sum(IIf([Date Modified]=Date()-3,1,0)) AS Day3,
Sum(IIf([Date Modified]=Date()-2,1,0)) AS Day2,
Sum(IIf([Date Modified]=Date()-1,1,0)) AS Day1,
Sum(IIf([Date Modified]=Date(),1,0)) AS Day0,
Sum(IIf([Date Modified]>Date()-7,1,0)) AS Last7Days,
Sum(IIf([Date Modified]>Date()-30,1,0)) AS Last30Days
FROM Imported
WHERE (((Imported.[Modified By]) Is Not Null))
GROUP BY Imported.[Modified By];
