Forms :: Navigation Form With Subform

I have a Navigation form that has multiple forms that I linked to buttons at the top. They open the forms (now subforms) for the most part just fine. The issues come into play when I click on a combobox that pulls from a query of a table. Once this data is selected I have another combo box that is supposed to be filtered based off of the original combo box selection. Everything works on the original forms but once they are in subform form I get the error "Forms!MGM Search Form!STATE" which is the name of one of the forms and its asking for me to enter a parameter value for the query. Its almost like its not requerrying the data like it does in the original form

Private Sub State_AfterUpdate()
me.Facility.Requery
End Sub

basically the first combo box is a list of states and then the second combo box is a list of facilities in that state. Once you click on the state in the first combo box it filters the facilities in that state. But again once in the subform view it will not requery.
