How to add Touched events to a entire model using one script? (Answered)

I am attempting to make one script that takes all the parts in its parent model and give them the ability to kill a player on touch.

Here is what I have...

parts = script.Parent:getChildren()

function onTouch(part)
if part.Parent:FindFirstChild("Humanoid") ~= nil then
part.Parent.Torso:BreakJoints()
end
end

while true do
for x = 0, #parts,1 do
	parts[x].Touched:connect(onTouch)
end
end

Error: 00:20:12.146 - Workspace.Dog.Death:11: attempt to index field '?' (a nil value)

I am curious if I should proceed in a new direction in doing this. I would rather not copy and paste one script in every individual part. I feel this would just make it easier if it can be done.

In general, I would just like to know how to attach Touched events on every part in a single model with one script.

Thanks! :)
