A frame is not a valid member of another frame?

Okay, so I have a script that makes a GUI change another GUI's text when clicked on. Here is the script:

local Weights = game.ReplicatedStorage:WaitForChild('Weights')
local Weight = Weights:WaitForChild('Weight25')
local BuyButton = script.Parent

BuyButton.MouseButton1Click:Connect(function()
    local ItemsFolder = game.ReplicatedStorage:WaitForChild('Weights')

    for i,Item in pairs(ItemsFolder:GetChildren())do

        local name = Item.Name
        local price = Item.ShopGuiInfo.Price.Value
        local desc = Item.ShopGuiInfo.Description.Value


        local WeightInfoMenu = script.Parent.Parent.Parent.Parent.Parent.WeightsFrame.WeightsMenu.WeightInfoMenu

    local ItemName = WeightInfoMenu.ItemName
        local ItemName =        script.Parent.Parent.Parent.WeightsFrame.WeightsMenu.WeightInfoMenu.ItemName
        ItemName.Text = 'Test Text'
        print(ItemName.Text)
        local WeightSpeed = WeightInfoMenu.WeightSpeed
        local ItemDesc = WeightInfoMenu:WaitForChild('ItemDescription')
        local WeightPrice =  WeightInfoMenu.WeightPrice

    end

end)

Here is my issue. At the line where it says:

localWeightInfoMenu = script.Parent.Parent.Parent.Parent.Parent.WeightsFrame.WeightsMenu.WeightInfoMenu

I am given an error that says:

WeightsFrame is not a valid member of Frame.Players.TheGamerGuy82.PlayerGui.Main.WeightsFrame.WeightsMenu

This script's parents, from top to bottom: Main, WeightsFrame, WeightsMenu, ScrollingFrame, WeightsButton25.

WeightsInfoMenu's parents from top to bottom: Main, WeightsFrame, WeightsMenu.

I am not sure how to fix this as I thought my syntax was correct.
