You can't make a timer run backwards, since the interval parameter won't acept negative values.

Why don't you just set your timer to 1000 miliseconds so that it expires every second, and in your when-timer-expired enter whatever code is necesary to make it look like your doing the count down. i.e

:global.v_secondsleft := :global.v_secondsleft - 1;
:blk_item := :global.v_seconds_left


You can do the very same thing to control the minutes. And finally a timer that expires after 10 minutes just to stop the whole thing.

That's way i would do it, unless there would be a clock component that could do what your trying to do, but I honestly don't know if there's any

Listen, you would have to declare :GLOBAL.v_secondsleft in your When-New-Form-Instance trigger like this:
:GLOBAL.v_secondsleft := 59;

And on the When-Timer-Expired you do the:
:global.v_secondsleft := :global.v_secondsleft - 1;

And display it on an item. you also have to check that after you reach 00, you reset it to 59.
Try it. It should work Smile

Hope I'm being helpful owais
Regards!
