What I had to do to get it to work was just query the DateAdd function then query that value back to another query to run the <=[Cdate] criteria! Now it works and I get the information that I need. But thanks so much for your help!

Sorry, I don’t have an answer. It should work.

I have read in the web some other people having similar problems. It seems to work when you use the DateAdd function in the WHERE clause with static values, but fails when using column names or parameters.

SELECT Student.ID AS Student_ID, Student.StudentID, Student.FirstName, Student.LastName, Student.Address, Student.Address2, Student.City, Student.State, Student.Zip, Student.PhoneNumber, Student.MobileNumber, Student.EmailAddress, Student.StartDate, Course.CourseNumber, Course.CourseName, Course.Required, Course.Certificate_ID, Certificate.ID AS Certificate_ID, Certificate.Certificate, Certificate.Length, DateAdd(“yyyy”,[Length],[StartDate]) AS CompletionDate
FROM (Certificate INNER JOIN Course ON Certificate.ID = Course.Certificate_ID) INNER JOIN (Student INNER JOIN Table1 ON Student.ID = Table1.Student_ID) ON Course.CourseNumber = Table1.CourseNumber
WHERE (((DateAdd(“yyyy”,[Length],[StartDate]))<[Enter Date]))
ORDER BY DateAdd(“yyyy”,[Length],[StartDate]) DESC;

Does this help?
