I am working with a countdown timer and have it set so that it is able to be set by the user. When the timer gets to 00:00 its supposed to say “done!”. For some reason I’m getting the “done!” right after I start the timer. After hitting pause and resume it shows my counter counting down but I’m not so sure that customers are gonna be cool with this. Can anyone tell why I’m having this problem? Thanks.

Chopping off the initialisation code confused me there as it too a while to notice your braces didn’t balance…
it looks like you are creating your counter and initialising it outside of both of the onclick functions. At this stage Length is zero.
when you click the start button length gets set to a valid time but the timer is not reinitialised so it starts with its previously set value of zero and fires onFinish straight away.
When you press pause the correct remaining time is calculated and which is then passed onto the new counter you create when you resume which then proceeds to count down normally.
Moving
counter = new MyCount(length, 100);up to directly afterdialog.show();}should ensure that the counter gets initialised when the set timer button is clicked and fix the problem.
