unique data in a table.

I have a database, and in it i have a problem.

I have a table, from wich data is entered via a form.

How can i get access to not allow duplicate entrys into the same row.

Eg

I have a space for two names. if you enter Mark into one, and try and enter
mark into the other, i want access to bring up a message box saying
"duplicate name entered."

Do you get what i mean, or do i need to be more descriptive.

Thanks!!

Mark,

You don't need two fields on your form! Go to the database window and the the
tables tab. Open your table in design view. Click on the fieldname where you
enter Mark. Go to the bottom - Field Properties - and click in the Indexed
properties. Select Yes(No Duplicates) in the drop down list. Access will now
throw up an error message when you try to enter a duplicate name in that field
on your form.

In the BeforeUpdate event of the second name text box check that the
value of the first text box is not the same:

IF Me.Name1 = Me.Name2 THEN
MsgBox "Duplicate name entered!"
Cancel = True
END IF
