Get player rank from HD Admin?

I have this function in a script that allows the player to bypass the anti-exploit if it returns true.

local function HasAdmin(id)
	for i = 1,#Administrators do
		if (string.upper(id) == string.upper(Administrators[i])) then 
			return true 
		end
	end 
	local player = game.Players:GetNameFromUserIdAsync(id)
	if game.Workspace:FindFirstChild(player) then
		if game.Workspace:FindFirstChild(player).Humanoid.Health < 5 then
			return true
		end
	end
	local checkModule = require(script.CheckRank)
	
	checkModule.checkRank(player) -- tried a module script bc all of the HD admin scripts were inside modules (idk how use modules. this might be wrong o-o)
	

--[[ First attempt. Didn't work 

	local main = _G.HDAdminMain
	local plrRank = main.pdata[player].Rank
	if plrRank >= 1.5 then
		return true
	end
]]


	return false 
end

I want it so if the players rank is higher than something then it will return true. This is what I have in my module script.

local module = {}

local main = _G.HDAdminMain

function module:checkRank(player)
	local plrRank = main.pdata.Rank
	if plrRank >= 1.5 then
		return true
	end
	return false
end



return module

I have looked through the code of HDAdmin. One reason your script isn't working is because your script runs before _G assign HDAdminMain to the MainFramework, and also because the data for the server is stored in main.pd[player]

local module = {}	 

function module:checkRank(player)
	local main = _G.HDAdminMain
	local plrRank = main.pd[player].Rank
	print(plrRank) -- Prints 5 for owner
	if plrRank >= 1.5 then
		return true
	end
	return false
end
 
return module
