Attempt to index string with 'Text"?

So I was working on my clicker game when I ran into an error saying, "attempt to index string with 'Text' and here is the code

local moreRebirthButton = script.Parent 
local infoHolder = moreRebirthButton.Parent.Parent.info

local price = infoHolder.Frame.TextLabel
local upgradeInfo = infoHolder.info
local upgradeName = infoHolder.Name

local Players = game:GetService("Players")

local player = Players.LocalPlayer
local upgradesFile = player:WaitForChild("upgrades")
moreRebirthButton.MouseButton1Up:Connect(function()
    local rebirthsButtonData = upgradesFile:WaitForChild("rebirthButtons")
    upgradeInfo.Text = "This will give you a boost!"
    upgradeName.Text = "Rebirth Buttons"
    price.Text = ((10)+(rebirthsButtonData.Value*10)).."Gems"
    if infoHolder.Visible == false then
        infoHolder.Visible = true
    end

    rebirthsButtonData.Changed:Connect(function()
        price.Text = ((10)+(rebirthsButtonData.Value*10)).."Gems"   
    end)
end)~~~~~~~~~~~~~~~~~
