DCount Criteria from Subform to Main form

[Shiller]

Expert,

I have an unbound text box on my Main form and I'm trying to pass
criteria to a DCount function from the subform to the unbound text
box on my main form. How do I go about doing that.

Thanks,

I have an unbound text box on my Main form and I'm trying to pass
criteria to a DCount function from the subform to the unbound text
box on my main form.

That's a little vague.

If the thing you want to pass is a number on the current
record in a subform text box and the DCount is in a main
form text box's control source expression:

=DCount("*", "sometable", "somefield=" &
subform.Form.textbox)
