Why is my script not working when clicked, and when Touched works?

So, basically, I'm making my own shop. Just starting from the basics for now. My shop works when I use a Touched event, but when I use a TextButton, NOTHING works. Here's my script:

local part = game.Workspace.surface
local db = true



function check(hit)
	local human = hit.Parent:FindFirstChild("Humanoid")
	local character = game.Players:GetPlayerFromCharacter(hit.Parent)
		if human then
			
			db = false
			
			if character.leaderstats.Money.Value >= 5 then
				
				character.leaderstats.Money.Value = character.leaderstats.Money.Value - 5
				
				game.Lighting.RocketLauncher:Clone().Parent = character.Backpack
				
				db = true
				
			else
				print("You need more money!")
	
			end
		end
	end


part.SurfaceGui.TextButton.MouseClick:connect(check)

All help is appreciated!

Try changing from

part.SurfaceGui.TextButton.MouseClick:connect(check) 

to

part.SurfaceGui.TextButton.MouseButton1Click:connect(check)
