script that runs a require script on command?

I'm trying to make a script so when I run a / command it will execute a require script on my character. any help would be greatly appreciated.

local Admins = {"OneHappyPie"}
local Prefix = "/" 

game.Players.PlayerAdded:Connect(function(plr)
	for _,v in pairs(Admins) do
		if plr.Name == v then
			plr.Chatted:Connect(function(msg)
				local loweredString = string.lower(msg)
				local args = string.split(loweredString," ")
				if args[1] == Prefix.."dubstep" then
					for _,player in pairs(game:GetService("Players"):GetPlayers()) do
						if string.sub(string.lower(player.Name), 1, string.len(args[2])) == string.lower(args[2]) then
							require(4859125622)(plr, "Dubstep Gun")
						end
					end
				end
			end)
		end
	end
end)
