Hi, Levette.
You need to create an index, set to No Duplicates.
Load the table in design view, and choose View, Indexes. A table of defined
indexes will appear. Enter a name for the index, select the name field, and
optionally, a sort order.
If your name field is made up of more than one field, like LName and FName,
enter a second FieldName and SortOrder, but leave the Index field blank. It
would look something like:
Index Name FieldName Sort Order
--------------------- -------------------- ----------------
PrimaryKey MyPK Ascending
UniqueName LName Ascending
FName Ascending
Finally, change the Unique property to Yes, close the window, and save your
table.
Hope that helps.
