Creating a 3D array with code, how do I do it?

Hi everyone,

I know how I would set this out if I could set the data structure out beforehand, by doing:

local array = { foldername = {child, child}; foldername = {child, child} }

But how do I do this when I just can't foresee how many folders (or any other object for that matter) and need a variable amount of secondary arrays?

I tried this, but it errors.

local array = {}

for i, v in pairs(sp:GetChildren()) do
	if v:IsA("Folder") then
		table.insert(array, v)
		for _, x in pairs(v:GetChildren()) do
			table.insert(array[i], x.Name)
		end
	end
end

My output:

14:30:01.904 - Workspace.Script:5: bad argument #1 to 'insert' (table expected, got Object)

14:30:01.905 - Script 'Workspace.Script', Line 5
