[AccessD] Restrict data entry from form into table

Chester
If you set an index on the date plus the second field and make it Unique
won't that do it? They'll still be able to select the 'wrong' value from the
dropdown but Access will error when they try to save that record. You can
have an error handler to intercept the errror and give a neater message if
you want to.
