Pomodoro Clock Resume Failure

I am attempting to utilize setInterval and clearInterval to pause and play the clock, however, I am unsure what is happening in this instance…

Here is the error I am receiving ’ 11. If the timer is paused and I click the element with id=“start_stop”, the countdown should resume running from the point at which it was paused.’

Specific error…
Pomodoro has started but time displayed is not changing: expected '00' to not equal '00' AssertionError: Pomodoro has started but time displayed is not changing: expected '00' to not equal '00'

Here is the code I have thus far…

Incorrect placement of subtraction of time, expected to be performed before display of time…
