Pretty sure you need an _in Timer1 call Start_ block. But I haven’t had much luck with timer’s myself! There’s some more info about timers here: > [@Creating a Counting Timer](http://community.thunkable.com/t/creating-a-counting-timer/322273): > > I am trying to learn to work with timers and I get that the IntervalMilliseconds value acts as a trigger event, but I want to put a timer in an app; either counting up or counting down, but I cannot seem to figure it out. I have found that Thunkable classic has a clock feature which works well in these situations, but am wondering if there is a way to do it with the timer feature that is currently available? > **[Timer Blocks | Thunkable Docs](https://docs.thunkable.com/timer)** I think the interval (in milliseconds) is how often the timer can create an event that you can use for whatever purpose you need (e.g. changing a variable by 1). --- _[View the full topic](https://community.thunkable.com/t/what-is-interval-milliseconds/806078)._
