(Solved)How do I fix the recursive function?

Hello, I'm doing a recursive function, on some models and inside there are other models and part, well then it throws me an error of stack overflow, and the script stops working, what can I do to fix it ?, I'm new and it's not that know a lot, thanks.

function ChildEdi()
	for i, child in pairs(model:GetChildren()) do
		if child:IsA("BasePart") then
			child.Touched:Connect(onModelTouched)
		elseif child:IsA("Model") then
			ChildEdi(child)
		end
	end	
end

ChildEdi(model)

The problem is that you are putting an argument into the function where no parameter exists. Simply add the parameter:

function ChildEdi(model)
    for i, child in pairs(model:GetChildren()) do
        if child:IsA("BasePart") then
            child.Touched:Connect(onModelTouched)
        elseif child:IsA("Model") then
            ChildEdi(child)
        end
    end 
end

ChildEdi(model)

Hope this helps and have a great day scripting!
