I have two queries in MS Access.  They both return an ID (primary key) for an individual.  How do I create a 3rd query that returns the ID from query 1 only if it does not exist in query 2?

This does'nt work.  It is asking me for a parameter value for Query1.

SELECT DISTINCT [Query1].ID AS Expr1
FROM [Query1] AS Q1
WHERE (((Q1.ID) Not In (SELECT [Query2].ID from [Query2])))
ORDER BY [Query1].ID;

No, it's the general form.  Take this:

SELECT DISTINCT [Q1].ID AS Expr1
FROM [Query1] AS Q1
WHERE (((Q1.ID) Not In (SELECT [Q2].ID from [Query2] AS Q2)))
ORDER BY [Q1].ID;


And replace FROM [Query1] and FROM [Query2] with the FROM clauses from your original queries

It is still asking me for a parameter value?  Why?

because one of the names within square brackets  is incorrect.
