VS 2005 Creating A Textbox List Using Textboxes As Input

What I'm trying to do is make a list of members in a read only textbox getting the data from two textboxes (first and last name) and a 'save' button.
I've made a class named 'Deltaker' (Members in english) to store data and a list 'resultater' (eng: results) using the 'Deltaker' class.

I'm trying to get user input from two textboxes 'tbxFornavn' and 'tbxEtternavn' and I use my class' public function 'Navn' to display it in the textbox 'tbxHistory'.

I've got a sub procedure to add the input to the list and clear the textboxes and enable another reset button.

So for the save button click event I run the sub procedure and I've written a for next loop to display the results from the list. The first name I enter is all good, but with the second name entry both the first and the second name gets listed as well as the first name that is already there. I thought about using the .clear function to clear the list after each input, but I also want to incorporate laptimes in the list and display the best time in a lable at the bottom of the form. Maybe also sort the list, so I need the data in the list to stay intact.

Public Class Form1
Dim resultater As New List(Of Deltaker)
Private Sub AddDeltaker()
