Here's what I tried before my ROBLOX Studio crashed, took a screenshot so sorry for the white overlay.

I've never used table.sort, table.concat, or tried to order a table from greatest to least. Let alone an entire UI. The names of the frames inside the "List" are numbers converted to int values as seen in the script. I've reread over the wiki's description over these and still couldn't grasp it. Could someone help me out? Really struggling with this q.q

I forgot to mention this is pretty much a leaderboard. So the player and their wins and displayed on a surface UI from greatest to least
This would do exactly that.
