Why won't my script save data to a table?
I'm making an advanced purchase script, but it isn't working. Instead of having to painfully type in a ton of numbers, you could just set the ID of an item and it would take that and put it in a table.

local ids={}
local items=script.Parent.Frame:GetChildren()
for i=1,#items do
ids[i].id=items[i].ID.Value --this line has an error.
ids[i].value=items[i].Name:sub(1,#items[i]-1)
end
local MarketplaceService = Game:GetService("MarketplaceService")
local plr=script.Parent.Parent.Parent.Parent.Parent
MarketplaceService.ProcessReceipt = function(receiptInfo)
if receiptInfo.PlayerId==script.Parent.Parent.Parent.Parent.Parent.userId then
for i=1,#ids do
if receiptInfo.ProductId==ids[i].id then
plr.leaderstats.Cash.Value=plr.leaderstats.Cash.Value+ids[i].value
break
end
end
end
return Enum.ProductPurchaseDecision.PurchaseGranted
end
Here's the error:
attempt to index field '?' (a nil value)
And this is what the Explorer looks like:
Player
PlayerGui
Menu
Menu2
Open
Buy Cash

Purchase --script is here.

Any ideas on how to fix this?

Yes. The problem is that you're trying to set id in and value in something that doesn't exist. When you're going through all the values in items, you are indexing that number in ids which is nil because the table is empty, and then you try to set the id and value of nil which you can't do.
To fix this you can replace your loop with this:
for i=1,#items do
ids[i]={}
ids[i].id=items[i].ID.Value
ids[i].value=items[i].Name:sub(1,#items[i]-1)
end
This fixes it by setting a the nil value to a table, so now, instead of setting id & value in nil, you're setting id&value in a table.
I hope I explained this good. I'm bad at explaining (if you couldn't tell.), the code should work anyway. Please give me a point or whatever they use here to show people that this is answered (if it worked).
