Need help with criteria for a query - want all records or selection from combo box

[Col]

I have a query with criteria that comes from a combo box on a form. I'd
like to set the query up so the user can either limit the criteria to
the selection in the combo box or the user can pull all records. Can't
figure out a way for the query to pull all records. Currently uses the
criteria [forms]![frmreport]![combo10]. I've tried a couple of things
to allow for the option of all records, but without any luck. Any
suggestions?

Switch the query to SQL View (View menu, in query design.)

Locate the WHERE clause.
It will be something like this:
WHERE ((Table1.Field1) = [forms]![frmreport]![combo10])

Change it to this kind of thing:
WHERE (([forms]![frmreport]![combo10] Is Null)
OR (Table1.Field1 = [forms]![frmreport]![combo10]))

If you have several of these, it gets messy to maintain.
For an alternative, see how the Search Form works here:

Another way to skin the cat
Put this in the criteria of the field that is based on the combo box

Like IIf(IsNull([Forms]![test]![Combo0]),"*",[Forms]![test]![Combo0])

Actually, this one fails to return the records where the field is Null.

Interesting,
Thanks for pointing that out Allen. I have always used that method on
required fields, so it never bit me.

Nice to know though. Thanks
