hello all! What this is warning problem? -- https://imgur.com/a/W5DUNvO

buyUpdate:

local player = game.Players.LocalPlayer
while true do
    wait(.1)
                if script.Parent.Parent.Parent:WaitForChild("Value"):WaitForChild("SwordBoost1") then
                local v = script.Parent.Parent.Parent:WaitForChild("Value"):WaitForChild("SwordBoost1")
                if player.Tools[script.Parent.Parent.Parent:WaitForChild("Value"):WaitForChild("SwordBoost1").SwordBoostParent.Value].Value == true then
                    if player.ToolEquiped.Value == script.Parent.Parent.Parent:WaitForChild("Value"):WaitForChild("SwordBoost1").SwordBoostParent.Value then
                    local toolTemplate = script.Parent.Parent.Parent:WaitForChild("Value"):WaitForChild("SwordBoost1")
                    local sel = toolTemplate:WaitForChild("Sel")
                    sel:WaitForChild("Stats").Text = "Equipped"      
                    else
                    local toolTemplate = script.Parent.Parent.Parent:WaitForChild("Value"):WaitForChild("SwordBoost1")
                    local sel = toolTemplate:WaitForChild("Sel")
                    sel:WaitForChild("Stats").Text = "Equip"                    
                 end
            end
     end
end

SeeStats:

script.Parent.MouseButton1Click:Connect(function()
    if script.Parent.Parent.Parent.Parent.Parent.Value:FindFirstChild("SwordBoost1") then
        local st = script.Parent.Parent.Parent.Parent.Parent.Value.SwordBoost1.SwordBoostParent
        script.Parent.Parent.Parent.Parent.Parent.Value.SwordBoost1.Visible = false
        script.Parent.Parent.Parent.Parent.Parent.Value.SwordBoost1.Parent = script.Parent.Parent.Parent[st.Value]
        local valueFrame = script.Parent.Parent.SwordBoost1
        valueFrame.Parent =  script.Parent.Parent.Parent.Parent.Parent:WaitForChild("Value")
        valueFrame.Visible = true
    else
        local valueFrame = script.Parent.Parent.SwordBoost1
        valueFrame.Parent =  script.Parent.Parent.Parent.Parent.Parent:WaitForChild("Value")
        valueFrame.Visible = true
    end
    end)

Where is problem warning or no have? A have to need fix problem warning? :)
