I haver this line currently:

=Sum(IIf([date]= <>,1,0))

I've tried replacing it with both:

=Sum(IIf([date]= ,1,0))

=Sum(IIf([date]= =,1,0))

Does'nt work?  Am I taking your instruction too literally ?

   =Sum(IIF([YesNoField],1,0))        Yes
   =Sum(IIF([YesNoField],0,1))        No
   =Sum(IIF(Not[YesNoField],1,0))     No
   =Sum(IIF(IsNull[YesNoField],1,0))  Null

the above is a good reference

Yes, the syntax used depends on the contex:
For null values these syntaxes have been used in different situations:
            = Null, Is Null; IsNull; nz

For not null:
            <> Null;Not IsNull; Is Not Null
Rey Obrero (Capricorn1)Commented:
if you are checking a date field you can use  Isdate([DateField]) to count the non empty field

SELECT Sum(IIf(IsDate([OrderDate]),1,0)) AS Expr1
FROM tblOrders;

also remember that "blank" can be NOt Null. An empty string "" is Not Null

YOu can test for empty with Not IsEmpty or <> ""

you can build a statement like

if myField Not isNull and Not isEmpty

but a better way is to simply evaluate the length of the field. if it is can be null or empty

If len(myField) = 0 then
Donald MaloneyConsultantCommented:

What your expression "=Sum(IIf([date]= <>,1,0))"

says  is:    Sum,  if field Date is equal and not equal then use numeric 1  else use 0.

It will always be 0 because the compare cannot be both equal and not equal.

Capricorns        =Sum(IIf(IsDate([OrderDate]),1,0))
says   Sum,  if field Date is a real date then use numeric 1  else use 0.

If you are comparing the field, in a query to a table/field called date then

sum (IIf ([TableField] = [date] ,1,0))
says  sum, if the table field is equal to the field date then use numeric 1  else use 0.
