Queries :: Query To Count Corresponding Records In Another Table

I'm trying to do a query to count corresponding records in another table. It works except for returning zeros. I've tried using NZ and switching the type of join, but to no avail.

Here's what I have:

Query A has 3 columns (FU kids)
AlphaID
DtcCtr (a Location Code)
DlsDtc (a Date of change)

Table A has many columns, but I'm only using a few. (dbo_MNCPSTNote)
AlphaID
DtcCtr (the same Location Code)
ServDate (the date I'm trying to count)

Here's what I have:

SELECT [FU kids].AlphaID, [FU kids].DtcCtr, Count(dbo_MNCPSTNote.ServDate) AS CountOfServDate
FROM dbo_MNCPSTNote RIGHT JOIN [FU kids] ON dbo_MNCPSTNote.AlphaID = [FU kids].AlphaID
WHERE (((dbo_MNCPSTNote.Center)=[FU kids]![DtcCtr])) OR (((dbo_MNCPSTNote.ServDate)>[FU kids]![DlsDtc]))
GROUP BY [FU kids].AlphaID, [FU kids].DtcCtr;

I want to know the count, including zero, of the number of records based on ServDate for each AlphaID in Query A.

I didn't create the tables and have no control over how they are designed/organized.
