Jim,

I wouldn't depend on the timer firing precisely at 1 second intervals as Hilmar suggests. I think you are better off doing something like:

thisform.tStart = datetime()
thisform.tEnd = thisform.tStart + nMinutes * 60

Then in the timer.Timer event:

lnSecondsRemaining = thisform.tEnd - datetime()
with thisform.txtLeft
   .Value = stuff( right( ttoc( {^2002-1-1 00:00:00} + lnSecondsRemaining, 1 ), 4 ), 3, 0, ':' )
   .Refresh()
endwith

>The timer part I understand. Making it display as 20:00 and then 19:59 and then 19:58 etc. is what I don't know how to do. If you do, a quick response will be greatly appreciated!
