guys on page 148

Public Overrides Function ToString() as String
returns Name & " (" & Email & ")"
end function

however at this point name is not defined and the structure will return nothing
you should change it to:

returns FirstName & "," & LastName & " (" & Email & ")"
End Function to get the names display in lstCustomers

or maybe i am missing something ?

Elad,

Name is a readonly property that returns the first and last name concatenated as a string.
