Help - Access none - Timer Over 2+Levels

Can anyone help me with this? I’m trying to make a timer, but want it to run over other levels, there is probably a much more efficient way of doing it than just a delay but I cba to search around basic tutorials that I have done before and was little/no help. So timing is off a bit anyway due to lag I think, but I attached the two variables to a text box binding(format text etc.) and it just shows up as 0 : 0 forever, I removed the gameinstance bit and just used the game mode blueprints variable s and that worked (thought won’t carry over as character resets I think?). Anyway any help at all will be appreciated or links to good tutorials.
