Get Value from Index on dictionary

Hello, I have been trying to get the value of an index from a dictionary but I have some problems with it:

-- variables
local player = game.Players.LocalPlayer;
local character = player.Character or player.CharacterAdded:Wait();
local shop = script.Parent;
local container = shop.ScrollingFrame;
local temp = container.Temp;
-- services
local rs = game:GetService('RunService');
local rep = game:GetService('ReplicatedStorage')
-- tables
local backpacks = {};
local array = {};
-- code
for i, v in pairs(rep.Backpacks:GetChildren()) do
	backpacks[v.Name] = v:GetAttribute("Order")
end
for key, _ in pairs(backpacks) do
	table.insert(array, key)
end
table.sort(array);
for i, key in ipairs(array) do
	local backpack = backpacks[key];
	print(backpack); -- prints 1,2,3 witch are the orders of the backpacks
end;

But I am trying to print the name of the backpack not the index.
How do I do that?
Thank you!

Was the ipairs intended ? Maybe try for i,key in pairs(array) do.

I tried it earlier but sadly it did not work.

Could you print backpack and screenshot what it says?

If you are trying to index an array it should be

for index, value in ipairs(array) do --An array
	local backpack = backpacks[index];
	print(backpack);
end;

Dictionaries would be:

for key, value in ipairs(dictionary) do --A dictionary
	local backpack = backpacks[key];
	print(backpack);
end;

The “key” variable is already the name of the backpack. Just do:

for i, key in ipairs(array) do
	print(backpack); 
end;

printing(backpacks[key]) -- finds the value associated with the name of that backpack, which is why it is returning the index.

Here is a screen shot of what it does:

Could you show me the children in the backpack?

Sorry, but do you mean this:

Hmmm on the line backpacks[v.Name] = v:GetAttribute(“Order”) you are indexing them by the child’s name?

I am trying to do something like this:

local backpacks = {
   ["A"] = 50

};

Ohh i see, you are actually indexing them using a string which holds another value in the table.

But how do I get the value of the index?

#15

Are you actually able to use in pairs for the backpacks table since the indexes are not integers?

The Array holds the actual indexes for backpack which are the names but you are printing the values of these indexes.

My solution is do local backpack = key and im sure it will print the name.
