I set up a table with an id number as primary key and shouldn't allow duplicated values in it. I designed a form based on this table and everytime that I input a duplicated value (which i may not know it's duplicated) the form does not alert me to this fact. If I close the form, it will close normally and will ignore the data. So in fact it's not allowing me to insert duplictaed value but it's not alerting neither that is a duplicate nor that will ignore that entry. This is really important, please help.
