Assigning Variables To A 2 Dimensional String Array?

I have a form that asks for a name, and a phone number, it has 3 buttons, a add customer button, show list button and an exit button. When the add customer button is clicked, it increments intCustomer variable, formats the phone number, makes sure only the first letters of the name are capitalized and creates an ID that is the first 4 letters of the name plus the customer number, the show list button takes ALL customers added to the array and displays them into a multi-line text box, like so:

ID Num Customer Name Phone Number
JOHN-1 John Harry Peters (111) 111-1111
Paul-2 Paul J Rodgers (111) 111-1111
Etc...

The area where I am completely lost in, is how to add the consecutive customers to the array, in the correct way. here is my code in its entirety

Public Class frmCustomerName
Dim intCustomer As Integer = 1
Dim names(9, 2) As String

[code]....
