Timer Count Up progressbar

Resolved

I'm trying to link a Linear ProgressBar to a timer Count UP
I set the timer to 60000 ms then I gave the ProgressBar a custom expression as you can see in the photos, it works fine a-t first but then I get this error it seems like the timer doesnt stop at 60000
The timer starts on page load !!!!


can anyone guide me on how to do this properly ?
and is there any way to change the timer format from mm:ss to ss:mm !
