Why won't this script work?

I created a car with a brick. The brick is grouped with the car to make a model. In the brick I have a ClickDetector and the following script.

location = script.Parent.Parent.Parent
regen = script.Parent.Parent
save = regen:clone()



function onClicked(hit)
    if hit.Parent.Humanoid~= nil then
        local player = game.Players:GetPlayerFromCharacter(hit.Parent)
        cash = player:WaitForChild("leaderstats").Cash
        if cash.Value >= 100 then
            cash.Value = cash.Value - 100
            back = save:clone()
            wait(1)
            back.Parent = location
            back:MakeJoints()
        else
            print("Not enough Cash") 
        end
    end
end

script.Parent.Touched:connect(onClicked) --might be issue

I am not sure how to read the output bar, but I may think the issue is with the last part of the script. If you could help, that would be great!

This is the whole output bar, if you would like to see it:

You are indeed correct. The issue is in line 23. Touched is an event of Part. If someone touches a Part, Touched is triggered. As i understood, your trying to detect rather a player has Clicked the part, right? So change line 23 to this:

script.Parent.MouseClick:connect(onClicked)
