Error in entity.lua

Having an issue with money printers, here is the error:

 [ERROR] lua/includes/extensions/entity.lua:157: bad argument #3 to 'SetFunc' (number expected, got nil)
1. SetFunc - [C]:-1
2. __newindex - lua/includes/extensions/entity.lua:157
3. DarkRPCreateMoneyBag - gamemodes/darkrp/entities/entities/spawned_money/init.lua:32
4. CreateMoneybag - gamemodes/darkrp/entities/entities/money_printer/init.lua:93
5. unknown - gamemodes/darkrp/entities/entities/money_printer/init.lua:77

It's referencing SetFunc, line 157 in entity.lua, so that can be found here:

	meta.__newindex = function( ent, key, value )
				
		local dt = datatable[ key ]
		if ( dt == nil ) then return end
		
		dt.SetFunc( self, dt.index, value ) <---- LINE 157
	
	end

I'm using the base DarkRP money printer code... Nothing changed. You can find that [URL="https://github.com/FPtje/DarkRP/tree/master/entities/entities/money_printer"]Here[/URL]. The money printers attempt to print money, but do not print anything and simply sit there and spark.

The problem is dt.index not having a number .. I peeked at the script but it seems like dt.index isn't given a number at any point.
I only saw this: "index = index" but since index isn't defined yet it sets it to nil.

There are two ways you can fix this problem:
- Defined index in the beginning of the script, like: dt.index = 0 Will define index as a number.
- Change "if ( dt == nil ) then return end" to "if ( !dt or dt.index == nil ) then return end" Will block the rest of the script if index isn't defended yet.

or both .. up to you :P

It is now saying this:

"if ( !dt or dt.index == nil or value ==nil ) then return end"

That fixed it! Thanks!!

So they print, but only in amounts of $0... interesting
