Clicking the Button dis-equips you wepon?

i want it so when you click the button it dis-equips you wepon.

You can unequip the player's tool by parenting it back from their character to their backpack, like so:

local plr = game:GetService("Players").LocalPlayer
button.MouseButton1Click:Connect(function()
	for i,v in pairs(plr.Character:GetChildren()) do
		if v.ClassName == "Tool" then
			v.Parent = plr:FindFirstChildOfClass("Backpack") or plr:WaitForChild("Backpack")
		end
	end
end)

You can use the :UnequipTools() method on the Humanoid of the player's character to achieve this.

-- in a LocalScript
-- local button = workspace.Button
local plr = game:GetService("Players").LocalPlayer

button.MouseButton1Click:Connect(function() -- when dey clik it
	plr.Character.Humanoid:UnequipTools() -- poof no moar toolz
end
