    Response.End
End If

theDate    = Now
DaysLeft    = DateDiff("d",theDate,CountdownDate) - 1
theDate    = DateAdd("d",DaysLeft,theDate)
HoursLeft  = DateDiff("h",theDate,CountdownDate) - 1
theDate    = DateAdd("h",HoursLeft,theDate)
MinutesLeft = DateDiff("n",theDate,CountdownDate) - 1
theDate    = DateAdd("n",MinutesLeft,theDate)
SecondsLeft = DateDiff("s",theDate,CountdownDate) - 1
%>
