ServerScriptService.Tool:19: attempt to compare string with number?

So I am creating a tool giver system, and there are a remote function and a local script. Whenever you click a button it should invoke the remote function but while doing this the script errors: 19:40:29.649 - ServerScriptService.Tool:19: attempt to compare string with a number.

Please Help -- Yours truly, suspectshot108

Local Script: Broken -- Line.. uhh well whenever u invoke the server.

local EventFolder = game:GetService("ReplicatedStorage").Functions
local RequestTool = EventFolder:WaitForChild("RequestTool")

for _,btn in pairs(script.Parent:GetChildren()) do
	if btn:IsA("TextButton") and btn.Name == "Item" then
		btn.MouseButton1Click:Connect(function()
			local Cost = btn:WaitForChild("Cost").Value
			local Name = btn:WaitForChild("Name").Value
			
			RequestTool:InvokeServer(Name,Cost)
		end)
	end
end

Script: Works Fine -- I think...

local EventFolder = game:GetService("ReplicatedStorage").Functions
local RequestTool = EventFolder:WaitForChild("RequestTool")

RequestTool.OnServerInvoke = function(Player,Name,Cost)
	if Player ~= nil then
		if Player.leaderstats and Player.Security then
			if Player.leaderstats.Bits and Player.Security.Bits then
				if string.match(Player.leaderstats.Bits.Value,Player.Security.Bits.Value) then
					local Ls = Player.leaderstats
					local Sy = Player.Security
					local Tl
					local Ne = "Bits"
					if Ls[Ne].Value and Sy[Ne].Value >= Cost then
						Tl = game:GetService("ReplicatedStorage").Tools[Name]:Clone()
						Tl.Parent = Player.Backpack
						wait()
						Ls[Ne].Value = Ls[Ne].Value - Cost
						Sy[Ne].Value = Sy[Ne].Value - Cost
					end
				else
					Player:Kick("Something is wrong with your leaderstats.")
				end
			end
		end
	end
end

So since the problem is in the server script on line 19, that means there's a flaw in . . .

if Ls[Ne].Value and Sy[Ne].Value >= Cost then

I think the problem is that you set Ne, to a string, aka a text, and Ls to leaderstats. I'm not sure what kind of object leaderstats is, but it's probably not a number. I'm also assuming that "Cost" is a number. So the error is saying you're trying to ask if a string is greater than or equal to a number. I don't really understand what exactly you're trying to do with the script, but just pay attention to that, and try to figure it out from there.
