This seems like it should be really easy and I think I'm just missing something really dumb.
I have a form that filters a report. At the top of the report I have a bunch of unbound text boxes that do simple things like count and sum. When I apply the filter to the report the text boxes update beautifully when their control source is something like
However now I want to apply a clause. If I do this: - =dcount("[num hatched]", "[tbl_nesting]","[num hatched]>0")
then I get a number but it's ALWAYS that number despite the filter. I want it just to count what's displayed after the filter but
doesn't work, just reports a false count.
What am I doing wrong?

There's quite a difference between the Aggregate functions and the Domain Aggregate functions.
In a report a Domain Aggregate function (DCount()) is self-contained. You must specify the record source etc. With an Aggregate function (Sum()) it refers to controls accessible (generally in the Detail section) in your report. Not fields notice (which are references to the underlying data source), but the controls.

You also mention filtering the report. As far as I'm aware, filtering is always applied to the recordsource, and is never effected by the values in controls. Does this help to understand?
Kind of. I had figured out that Count was going to work better than DCount, but I can't figure out how to phrase the statement I want with the rule applied (e.g. count, which works, vs. count where field value > 0, which doesn't work). Can you apply a rule like that in an aggregate function? I am useless with the expression builder - it is not very intuitive to me.
Got it. I needed an IIF statement. - =Count(IIf([Num Hatched]>0,0))

You did, but I suggest one more like : - =Count(IIf([Num Hatched]>0,1,0))
Can you translate that into a full sentence for me? I didn't fully understand even in the one that worked for me why 0 was used for "true" and not 1. In my binary world we always use 0 for false an 1 for true.
So my own example would read:
"If num hatched > 0, then false" which obviously isn't the case. And I'd read your statement to read:
"If num hatched > 0, then true, else false."
So why do the 0's and 1's get switched around? Of is mine just shorthand where the first/only comma is the else statement? Did I just answer my own question lol?
Actually A your statement didn't work? Now I'm doubly confused.

I recently tried to use code for "Use a multi-select list box to
filter a report" from Allen Browne in my database. I was able to add
the code and adapt it to my needs, however I am getting an error.
I click Ok and the report opens.
I look in the design view and the filter is there but the IN equals
"" (it is blank, the values are not in there)

I am trying to run a Apply filter for everytime someone opens Form_CC it will only show the Test (Test_ID) they are working on. This seems to be the closest I have gotten to filtering it correctly, however it doesn't work when the form is opened. Is there something I am doing wrong on this?
Private Sub Form_Open(Cancel As Integer)
DoCmd.ApplyFilter Form_CC.Form.filter = "Test_ID = 28"
Form_CC.Form.FilterOn = True
End Sub

I'm trying to filter a report with a date in VB code.
If I type an actual date bracketed with the pound symbol (i.e. #3-Jul-08#)
I can get the filter to work. I can't seem to get it to work by using a
variable. Am I trying to do the impossible?
I've tried using a date variable that I know contains a valid date. I've
tried bracketing it with pound symbols, single quotations etc. I've tried a
string variable and used the 'CDate'...

I know this is a simple function to program, but I'm a little rusty. I'm trying to set the "On Open" event on a report using a macro to apply a filter that I have saved as a query.
Can you please provide an example of how I should enter the information to run this filter when I open the report.
Thanks,
Ashley

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
