Help with ".."?

usally .. would add letters or numbers to something but it doesn't work here

local Frame = 1
player.Backpack.ChildAdded:connect(function(instance)
    local name=instance.Name
    if name==game.Lighting.E:GetChildren()[1].Name or name==game.Lighting.Q:GetChildren()[1].Name or name==game.Lighting.R:GetChildren()[1].Name or name==game.Lighting.F:GetChildren()[1].Name or name==game.Lighting.G:GetChildren()[1].Name then
        print(instance.Name .. " added to the backpack by item Clone")
    else
        print(instance.Name .. " added to the backpack by item pickup")
        player.PlayerGui.Invintory.Frame .. Frame.Frame1.Visible = true
    end
end)

it puts the red line under the .. saying expected = but i thought the .. added stuff but it doesn't here why
