Quick Question About My Distance Counter

So I used this distance counter that @weboha posted about (I'll put a screenshot and the .bbdoc below) and I was just wondering if anyone knew how I could change the "undefined" and "NaN" text to the level numbers (like level 1 to level 2).

Also, does anyone know how I could make the progress bar finish right as a level is complete?

Thanks

use this code for begin to game

if(Settings['level'] === undefined){
Settings['level'] = 1;
}
