How do i make a timer go between levels?

In my game I want the time on the timer to transfer between levels. for example If the timer starts at 1200 seconds and goes down 30 seconds I want the time in the next level to say 1170 seconds. Is there a way to do this or something similar?

Open the properties of the block containing your timer, and set it to “Keep between levels” this way, the object will not be destroyed when switching levels. Just make sure you don’t add it again to the second level.

thank you
