#ERROR in Sub - Report

I am in need of much help here.... kind of new to sub-reports.
My main report works fine and I have the sub report linked fine.

The problem is when there are no records in the subreport

Ok I have a sub-report that the record source is a sql

SELECT id,count(datemailed) as DateLetterMailedOut
FROM tblProduct
WHERE ContactType = "Mail"
GROUP BY id;

and when there are records the text box is populated.
what I want to be able to do is when there are no records found to show
0 (Zero) as the count

I tried putting in the control source of the text box

=iif(isnull([DateLetterMailed]),0,[DateLetterMailed])

then I tried
=iif(isnull([DateLetterMailed]),"0",[DateLetterMailed])

then I tried
=iif(isnull([datemailed]),0,[datemailed])

and I tried
=iif(isnull([datemailed]),"0",[datemailed])
and none of these worked.....

If anyone knows what I am doing wrong or has another solution, PLEASE HELP!!!

Thanks
Andrew

Well one clue that the syntax is wrong is when it does not capitalize the "I" in Iff

So try "Is null" as two words not one "isnull"

Second the quotes "" for the Zero are only needed if the DateLetterMailed field is a String. If its a number then you don't need quotes.
And Get the exact spelling of the field from the table or somewhere and paste it in the Windows clipboard or even in a Blank Notepad doc so you are 100% sure its spelled correct. And then paste it in your code by pressing Ctrl-C when you need to.

Also make sure that you infact have the DateLetterMailed field in your query if that what you are using.
