Why are the sub-tables of this table not being recognized?

So I have a dictionary for storing asset IDs and BodyColors returned by the Players:GetCharacterAppearanceInfoAsync() function:

local Data =
{	
	Assets =
	{
		Hats = {},
		TShirts = {},
		Shirts = {},
		Pants = {}
	},
	
	BodyColors =
	{
		Head = {},
		Torso = {},
		LeftArm = {},
		RightArm = {},
		LeftLeg = {},
		RightLeg = {}
	}	
}

Running print(data) prints in the output
table: 00000200066DBCB0, which is expected behavior.
But when I try to print(data[1]), theoretically, I should be having another table print because table[1] would lead to the Assets subtable, but instead I get nil printed.

Here’s the actual ModuleScript the data is contained in (this isn’t related to DataStore):

-- Module to store data.

local DataStorage = {}
local MarketplaceService = game:GetService("MarketplaceService")

local Data =
{
	Assets =
	{
		Hats = {},
		TShirts = {},
		Shirts = {},
		Pants = {}
	},
	
	BodyColors =
	{
		Head = {},
		Torso = {},
		LeftArm = {},
		RightArm = {},
		LeftLeg = {},
		RightLeg = {}
	}
}

return DataStorage

Here’s the result of printing this table:

print(Data, Data[1])
> table: 00000200066DBCB0 nil

Any help? Am I not understanding dictionaries correctly? I looked on the wiki for tables and it doesn’t seem to highlight this particular issue. I also tried enclosing the sub-table names with brackets and quotes, but that netted the same result. Is it because there are no keys inside of the sub-tables?

You are indexing it incorrectly, here try this

This is due to the fact that 1 is not the key.

Look at the following examples.

local t = {
    {"thing","thing2"}
}

Printing t[1] would print the memory address, as expected. However…

local t = {
    subtable = {"thing","thing2"}
}

Printing t[1] in the above example would come out to nil because the key isn’t actually 1, it’s subtable. Printing out t.subtable or t["subtable"] would give you the sub table.

Ah. Thanks.

No problem. I’d recommend looking at the Lua tutorial on tables for more information on arrays (keys ascending from 1) and dictionaries (string keys).
