What am I doing wrong with this stringvalue detection script?

for i, v in pairs(table of stuff, each of the stuffs having a StringValue object in them called GUIType) do
    print(v.GUIType.Value) -- 'TitleScreen' for all of them
     if v.GUIType.Value == 'TItleScreen' then -- Returns false, even though it is in fact TitleScreen
        v.Visible = false
    end
end

Pretty self explanatory. halp
