How can I make my GUI hover over failproof? [answered]

I have a GUI where each time I hover over a button, it highlights it by creating a little bar beneath it, which gets removed when the mouse leaves, however if you spam wipe your mouse over all the buttons, the bar sometimes stays.

The code which handles the creation and tweening,

local options = script.Parent.Options

for i,v in pairs(options:GetChildren()) do
    if v.Selectable == true and v:IsA("TextButton") then
        v.MouseEnter:Connect(function()
            print(v.Name)
            frame = Instance.new("Frame")
            frame.Visible = false
            frame.Parent = options
            frame.Size = UDim2.new(0, 0,0.015, 0)
            frame.BackgroundColor3  = Color3.fromRGB(255,255,255)
            frame.BorderSizePixel = 0
            frame.Position = UDim2.new(0.191,0,v.Position.Y.Scale + 0.13,0)
            frame.Visible = true
            frame:TweenSize(UDim2.new(0.645,0,0.015, 0),"Out","Linear",0.3)
        end)

        v.MouseLeave:Connect(function()
            frame:Destroy()
        end)
    end
end

How can I add to my code to make sure that this doesn't occur? Thanks.

Ok I made the frame that was being created be named (v.Name.."-Frame") and each time I ran the MouseEnter event I'd check if (v.Name.."-Frame") already existed, and if it did, I made the script delete it. Please still feel free to answer or comment with alternative solutions. Shrilleh 68 — 5y

I would use TweenService for any new work. It has parameters built it to prevent this, unlike :TweenSize / :TweenPosition / :TweenSizeAndPosition MessorAdmin 598 — 5y

    if v.Selectable == true and v:IsA("TextButton") then
        v.MouseEnter:Connect(function()
        if options:FindFirstChild("Frame") Then options.Frame:Destroy() -- This Should Work
            print(v.Name)
            frame = Instance.new("Frame")
            frame.Visible = false
            frame.Parent = options
            frame.Size = UDim2.new(0, 0,0.015, 0)
            frame.BackgroundColor3  = Color3.fromRGB(255,255,255)
            frame.BorderSizePixel = 0
            frame.Position = UDim2.new(0.191,0,v.Position.Y.Scale + 0.13,0)
            frame.Visible = true
            frame:TweenSize(UDim2.new(0.645,0,0.015, 0),"Out","Linear",0.3)
        end)

        v.MouseLeave:Connect(function()
            frame:Destroy()
        end)
    end
end

When you hover over a new button and there is still a frame it will delete it otherwise that line of code is ignored.
