"IF" statement not working properly?

Hello, im making a touch event where when a player touch the part, it looks in the player's gui to see if a certain value is named the same as the one in the part and if it isn't then it adds a new button but now it adds a new button even if there is the same value

db= false 

function handleTouch(otherPart)
	local character = otherPart.Parent
	local humanoid = character:FindFirstChild('Humanoid')
	local player = game.Players:FindFirstChild(character.Name)
	local gun = script.Parent.Parent.WepName --this is the first value
	if humanoid and db == false then
		db = true
		local buttons = player.PlayerGui.Weapons.Frame:GetChildren()
		for i = 1,#buttons do
			if buttons[i].ClassName == "ImageLabel" then
				if buttons[i].WepName.Value ~= gun.Value then --here is the part where it looks if it has the same value or not but even when its the same it will clone the button when it should only clone it if it isnt (~=)
					local newbutton = player.PlayerGui.Weapons.Frame:FindFirstChild("Button 1"):Clone()
					local num = tostring(i)
					newbutton.Name = "Button "..num
					newbutton.Parent = player.PlayerGui.Weapons.Frame
					newbutton.ButtonNumber.Value = num
					newbutton.Ammo.Value = 50
					newbutton.WepName.Value = gun.Value
					newbutton.Number.Text = num
				else
					buttons[i].Ammo.Value = buttons[i].Ammo.Value + 50
				end
				script.Parent.Parent.PrimaryPart.Transparency = 0.6
			end
		end
		wait(5)
		script.Parent.Parent.PrimaryPart.Transparency = 0
		db = false
	end
end
 
script.Parent.Touched:connect(handleTouch)
