This search script isn't working?

I've made this yesterday, then I forgot to save my studio and made it again but this time a little better. When I try to search "Wood" or anything else that's searchable, it says "Type here is not a valid member of ScrollingFrame" (Type here is the acutal text of the textbox)

My script:

bar = script.Parent.Parent.SearchBar
text = bar.Text
button = script.Parent
frame = script.Parent.Parent.ScrollingFrame
dirt = frame.Dirt
grass = frame.Grass
sand = frame.Sand
ice = frame.Ice
wood = frame.Wood
stone = frame.Stone
all = frame:GetChildren()
button.MouseButton1Click:connect(function(search)
    stone.Visible = false
    dirt.Visible = false
    grass.Visible = false
    ice.Visible = false
    sand.Visible = false
    wood.Visible = false
    wait(.1)
    frame[text].Visible = true
end)
