"Keep is not a valid member of Part"?

function onTouch(obj)
if obj.Parent:findFirstChild("Humanoid")~=nil then
p=game.Players:findFirstChild(obj.Parent.Name)
if p~=nil then
if p.TeamColor == BrickColor.new("Bright red") then 
backpack = p.Backpack.GK:GetChildren()
for i, v in ipairs(backpack) do 
if v.ClassName == "LocalScript" then v.Disabled = false
end
end
end
end
end
end
script.Parent.Touched:connect(onTouch)

hi guys, this script is suppose to make disabled = false in the local scripts inside a tool however it does not work!! please help me the output says

"Keep is not a valid member of Part" line 4

but this is weird because I have another script that does the exact same thing but it makes the scripts disabled instead of making them undisabled and that works perfectly please help
