Korblox Right Leg GAMEPASS

If you own the game pass you have the Korblox Right Leg, my script that I have is working but only with R6 when I need it to work with R15, as my game is better looking with R15 avatars.

I did not make this script someone helped me out by making it for me and It works but not with R15 and that’s what I am hoping someone could figure out and help me fix this problem.

In ServerScriptStorage the actual script is in there with the “Korblox Deathspeaker Right Leg” mesh placed inside the script like the picture below:

The script:

local service = game:GetService("MarketplaceService")
local Gamepass = game:GetService("GamePassService")
local PassId = 15888030

		if (service:UserOwnsGamePassAsync(plr.UserId, PassId)) then
			local leg = script["Korblox Deathspeaker Right Leg"]:Clone()
			leg.Parent = char
			local isr15 = char:FindFirstChild("LeftUpperLeg")

I believe you have to use HumanoidDescriptions (however idk how).
