Hi! I’m trying to make a step tracker where when you press the start button on the 2nd screen, a timer fires but you only see the time elapsed in the 3rd screen (stats)

It isn’t necessary to add the `update time` since you already have the `updateElapsedTime` function in your code. As long as your timers are starting at 00:00:00, and your timer is counting up by every **second** , it should be fine. Milliseconds can also count too.

I can provide an example below for you:

Set your update time function:

```auto
function "update time"
  forever:
    wait 1 seconds
    change app variable formatted_seconds by 1
  forever:
    wait 60 seconds
    change app variable formatted_minutes by 1
  forever:
    wait 3600 seconds
    change app variable formatted_hours by 1

```

Formatted Time function:

```auto
function timer:
  if app variable TimerRunning = true:
    format time
    set Time_text text to:
      join:
        formatted_hours, ":", formatted_minutes, ":", formatted_seconds
    else:
      set formatted_hours to 0
      set formatted_minutes to 0
      set formatted_seconds to 0

```

Another error you’re probably encoutering is the zeroes. You’re combining a string and a number, which is not exactly ideal. Instead use number variables, and that might make your process a little better 🫠

If you could also tell me where you are testing this app on, that may be more useful to my understanding.
