Update:

When I close the Form and come back into it, everything is there in the SubForm like nothing ever happened...????

What code do you have to do the Search? Please post it.  John

Sorry about that, here is the CODE:

Private Sub SearchAirportNameBtn_Click()
    Dim S As String
    
    S = InputBox("Please Enter Airport Name", "SEARCH For A Specific Airport Name")
    If S = "" Then Exit Sub
    
    Me.Filter = "AirportName LIKE ""*" & S & "*"""
    Me.FilterOn = True
End Sub

...attachements

Update:

I also have another Search Macro (Embedded Macro) on the same form, when I use that I don't have a problem with the SubForm Data disappearing.  Why is that?

Update:

I just realized something while I was racking my brain out here...it looks as if the SubForm is being filtered as well as the Form itself.  I clicked on the filter button itself and low and behold the data showed back up!  Someone needs to explain to me why this is happening.  I'm sure there's someone out there that's come across this as well.  Is it a fluke?  Or is it part of the programming of ACCESS DB itself?

Is there a way that that filtering of the SubForm can be denied and or corrected?
