Why this script is not working? i tried everything

owner = script.Parent.OwnerName
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()


mouse.Button1Down:connect(function(hit)
		local check = hit.Parent:FindFirstChild("Humanoid")

			local thisplr = game.Players:findFirstChild(hit.Parent.Name)
				if owner.Value == thisplr then
					script.Parent.Locked = false
				else
					script.Parent.Locked = true
				end
end)

So this is a LocalScript, this localscript is inside a part called "brick". The brick has stringvalue of OwnerName and value of Player1, i just directly Assigned it for testing. So, When you click it and your name is not Player1 the brick will remain locked, but if your name is Player1 then locked is false. But it's not working. Please help.

First off, please fix your title. Your question title would most likely not attract scripters, since it's too broad. To detect when someone clicked a Part, you'd used the MouseClick Event. To do that, you'd need to insert a ClickDetector into the part. Also, there's no need for the script to be a LocalScript. With that in mind, here is your fixed script:

owner = script.Parent.OwnerName

script.Parent.ClickDetector.MouseClick:connect(function(plr)
	if plr.Name == owner.Value then
		script.Parent.Locked = false
	else
		script.Parent.Locked = true
	end
end)

One last note: Be sure to search your question before asking it. I've answered these type of questions numerous time. Instead of including the "Locked = true" part, just search about a ClickDetector, or how to get who clicked a click detector.
