This function will return a true value if the table exists in the database;
false if not.
Public Function TableIsHere(strTableName As String) As Boolean
Dim tdf As TableDef
TableIsHere = False
For Each tdf in CurrentDb.TableDefs
If tdf.Name = strTableName Then TableIsHere = True
Next tdf
End Function
