problem with PK and Relatioships in subforms

[Nokia N93]

i attached a file

i want to enter many problems to the same phone number,,, but not at the same time
meaning that i may enter a problem and after a month ago i entered the same number, i want the subform to retrive the old problem
i tried to make a caller ID as the relatioship but it didn\t work


i tried to make the phone# as the PK but when i entered the seconed problem an error appeared (The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. (Error 3022))
how can i solve this problem?

Your PhoneNumber (Customer??) has a 1:m relationship with Problems. Customers in one table and Problems in another table with the PK of the Customers table and a FK in the Problems table. Then use a Form/SubForm to display the results with the Cistomer table for the MainForm and the Problems for the SubForm.

yes i already done that
i mean if the same number after 20 records for example called again , i want when i enter the number to retrieve the problem which is already done but when i need to enter the seconed problem
this error occurred (The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. (Error 3022))

Your MainForm should have a ComboBox that "Looks up an existing record" instead of a TextBox that is bound to the PK of that table. The cbo wizard know how to create one of these just add the cbo to the form and select Option #3. Use the NotInList event to add a record if it cannot find an existing one.
