I'd create a textbox in the form footer of the subform what does the count.
It's control source would be something like this:
=Count([SomeFieldName]).

Assuming you named the textbox txtSubCount, you can reference this field on
the main form in an unbound text box like so:
=[Forms]![Form1]![subControl1].Form![txtSubCount]

The above assumes your mainform is called "Form1" and your subform CONTROL
is named "subControl1". Modify it to match your form/control names.

On my website (www.rogersaccesslibrary.com), is a small Access database
sample called "SubformReference.mdb" which illustrates this and other ways
to reference controls on subforms and subsubforms..

But it still return me #Error,why?.Other function like Max,Min,Avg
works well in my subform footer.Strange isn't it?
