Stop Form_Timer from running

Question

Thanks for taking the time to read my question.
I have a form with the TimerInterval set to 1000. I want the form to count down by seconds by an amount set by the user. At the moment I have a field on the form in which the user can enter, in minutes, the amount of time the countdown should last.
my problem is, if the user updates the value, how do I get the Form_Timer to start all over again and keep running. I can call Form_Timer form the afterupdate event of the field, but then Form_Timer only fires once... If I change to design view and back
to form view the Form_Timer fires properly again with the new value (It's stored in the table that the form is linked to: recordsource). So then I thought, I could close the form and open another form that I could save the minutes in, but my button to close
the form will not fire because the Form_Timer code is constantly running (every second).
The form is set to Border Style = none, so the Close button is not visible.
Is there a way I can solve either issue?
Thanks,
Brad

Try resetting the timer interval to 0 then back to 1000
Here's a Q&D of a field (Text0) that will take a number and counts it down to zero:
Private Sub Form_Timer()
    If IsNull(Text0) Then Exit Sub
    If CLng(Text0) <> 0 Then
        Text0 = Text0 - 1
    End If
End Sub
Private Sub Text0_AfterUpdate()
    If IsNumeric(Text0) Then
        TimerInterval = 0
        TimerInterval = 1000
    End If
End Sub
Even while the timer's running you can change the value of Text0, however I recommend having the value you enter in one filed while another field displays the countdown value.
