Not sure I understand the question.

 If your basing this on a form control, it's:

 =Forms![myForm]![myFormControl] or Forms![myForm]![myFormControl] Is Null

 When you save the query, Access will re-format that splitting the check of Is Null off on a separate column.

  You can also use Like, but it is not as efficient.

1. You have no count query. If you had, it wouldn't return Null for no records to count, it simply would return no records.

2. Your function EXPORT_IDS makes no sense, as it takes no parameters and always returns Null.

3. Thus, it makes no sense to call InStr(EXPORT_IDS,n) in your query, as it will always fail.
If you called InStr(Nz(EXPORT_IDS),n) it would not fail, but a zero-length string will never contain any other string, thus the returned value will always be 0 (zero).

4. Thus, testing for 0 > 0 will never return records

You can have a query like this that will return a count for an inputted number or the total count if the parameter box for MaxIDS is empty:

SELECT Count(Table1.ID) AS CountOfID
FROM Table1
WHERE Table1.IDS >= Nz([MaxIDS],[IDS]);
