Thanks for that I'll have a look at the link.
I've just run the code but nothing is happening, the table I want to insert into is not being updated. Initially I had the wrong table to insert into but having changed it there's no action.
Here is what I have:
Private Sub Command7_Click()
Dim strSQL As String
strSQL = "INSERT INTO Tbl_Tracking (ID, Location) " _
& "SELECT ID, '" & Forms!Frm_Booking.Txt_Location & "' " _
& "FROM Tbl_Display"
CurrentDb.Execute strSQL
End Sub
Thoughts?
