aspx_beginners thread: for loop question

in this code snippet from page 236 of 'Beginning ASP.NET 1.0 Using C#' I
don't understand where the for loop resets itself. Any direction would be
most appreciated...
<script language="C#" runat="server">
void Page_Load()
{
int number, counter;
if (Page.IsPostBack)
{
number = Convert.ToInt32(NumberAttendees.SelectedItem.Value);
Message1.Text = ""; //reset here BEFORE going into the loop
for (counter = 0; counter < number; counter++)
{
Message1.Text += "Attendee Name _________________ <br /><br />" +
"Attendee Age __________<br /><br />
/*on second or third iteration, why doesn't Message1.Text get
bigger and bigger? ie. adding the first iteration to itself and then the
second and so on? I don't see where it is reset once in the loop??*/
}
}
}
</script>
<html>
...
<form>
...
<asp:label id="Message1" runat"server">
</form>
</body>
</html>

Does it have anything to do with the un-terminated string right before the
comment?
"Attendee Age __________<br /><br />

Sorry, that was just a typo when I was trying to clean up the size of the
code by stripping some stuff out. My code here has the terminating ".
thanks.

I understand it now after some help. I thought that the function would
print to screen after every loop not just at the end.
