It is possible for the same Form to be linked to two tables [or queries] by changing the 'Record Source' property of the form using VBA code.
For instance, I just put a Command Button on a Form and put this code in there:
Code:
Private Sub Command30_Click()
Me.RecordSource = "QryParameter_2"
End Sub
The Form's original Record Source [when it opens] is 'QryParameter'. But you can just as easily have two different tables.
I hope this gives you something to work on. Let me know if you need any other help.
