dCount causing Run Time Error - 3078

[alktrigger]

I am attempting to enable/disable a button based on the results of a query based subform. I am unsuccessful in the various attempts I have made.

Everytime I run this I get an error regarding the object that it is pointing to in this case sfrRMUDayEdit

Private Sub cmdShowData_Click()
    DoCmd.requery ""
    If DCount("*", "sfrRMUDayEdit") = 1 Then
        [Forms]![frmRMUDayEdit]![cmdAmmend].Enabled = True
    End If
End Sub

"sfrRMUDayEdit" needs to be the name of a table or query. It sounds like it's a form.
