Variable on scoreboard

[late aspen]

        set line 4 of loop-player's scoreboard to "&7>>  Border: %{_border}%"``` so this is partial of my scoreboard skript dont judge cuz its loop ik it causes lag  but idk how to create a variable, add a number to it and have that number show on scoreboard. I tried setting the {_border} to 16 with no errors but its not working can anybody help?

_ means it's a local variable so if you're setting it somewhere other than in the leaderboard code it won't show

you'd want to do {border}
