(see my other question first) Error with equipping tools?

Here's a link to what happened. https://gyazo.com/ca48a44cccfdf1e76d47a3ee2113267f

I made a transparent Part grouped inside my Meshpart to use as a handle. I used this script to forcefully equip it to you when touched. (I put the script inside the transparent Part.)

script.Parent.Touched:connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") then
        hit.Parent.Humanoid:EquipTool(game.Workspace.PortalGun)
    end
end)

Help me out a bit, i cant seem to figure out what's wrong.
