Timer to continue ticking [RESOLVED]

[martw]

OK, I know I'm full of problems, but please bear with me. I appreciate the help.

OK, I have a Timer. I know that in VB6 it was very different, but in VB.NET it appears that once the timer reaches it's interval, it stops ticking. Am I right? Well I'm having trouble with it and that matter. I have a code that goes like this:

Private Sub tmrTimeLeft_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrTimeLeft.Tick
        Dim TimeLeft As Integer = 180
        TimeLeft = TimeLeft - 1
        lblTimeLeft.Text = TimeLeft
    End Sub

And in the form Activated event, it is supposed to enable the timer.

I don't get what is wrong. I see the label change to 179 from 180 and that is it. If you help, I would appreciate it if you don't do the whole thing for me, as this is part of a school assignment and I don't want to have to take code of people. Thanks.
