Query by form, multiple criteria

[sxysiv]

Hello, I have a problem with returning records when I try to run a query by form. I have a form that provides my search criteria with two buttons that run a Query-to-table or a Query-to-report. Pressing either of these buttons will return an empty table or an empty report, when there should be data showing up.

My first unbound criteria is picked from a combo box, the value is named "QuarterName." (An example of a possible value is: MAT Internship)

The next three unbound criteria are blank, user fill-in boxes with the quarter date, named "Quarter 1,""Quarter2," or "Quarter3." (for example, one would enter a value like this: 200451 --> which means the Autumn quarter of the 2004-5 school year)

I need to search for a quarter name, and the specific dates those quarters where taken in; as in, searching for people that have taken the "MAT Internship" quarter, in 200451, 200452, or 200453. So, this is a QuarterName AND (3 OR options).

Here is my query setup in SQL:
------
SELECT StudentQuarters.quarter_name, StudentQuarters.quarter, Students.SPU_ID, Students.SSN, Students.program, Students.first_name, Students.middle_name, Students.last_name
FROM Students INNER JOIN StudentQuarters ON Students.SPU_ID = StudentQuarters.SPU_ID
WHERE (((StudentQuarters.quarter_name)=[Forms]![frm_Student_by_quarter]![QuarterName]) AND ((StudentQuarters.quarter)=[Forms]![frm_Student_by_quarter]![Quarter1] Or (StudentQuarters.quarter)=[Forms]![frm_Student_by_quarter]![Quarter2] Or (StudentQuarters.quarter)=[Forms]![frm_Student_by_quarter]![Quarter3]));
----
Can someone please tell me why the query will run, but show me no records at the end, when I know for sure that there is data that needs to show up?

Thank you so much in advance!
