This is what I was trying to get at earlier; I suspected that the record was there, just not where you expected it to be! You say you're adding data to three separate tables, so I assume the form is based on a query. If you go to the Query Tab and open your query in Design View, you can sort on any field you want and the sort will show in your form. You can even use multiple fields to sort, if yu want. The only thing to remember in a multi-field sort is that Access moves left-to-right when sorting. For instance, if these fields appeared like this
Customer City State
and you want to sort by State then by City then by Customer, you'd need to re-arrange your fields like this
State City Customer
