Kill door please!!

I am making a star wars game, and you start out with a gun, and you can buy others... i already have the money-for-kill script done, but im trying to put in ranks~ so if they had 50 kills, they were rank 1 or something... anyway, the money door takes away the points, but i dont want this one to, so bacisly heres what i want:

-A rank and points leaderboard, with rank going up by 1 every 50 kills

-A door that checks your rank, DOESNT SUBTRACT ANYTHING and lets you in if its high enough

Whoever makes this gets Super VIP at the place, which has, not only infinite money... but tons of things not available to players

i have the door and but the leaderboard keeps on braking

i think I could make a leaderboard

You guys it suo! easy
